From a $7 Add-On to a Free, Editable, 5-Language Audio Tour of 384 Acres

The brief

Mount Vernon is a 384-acre estate with 26 historic structures — gardens, tombs, a working farm, a museum, a library, a distillery, a gristmill — and the average guest spends three to four hours on the grounds. The places we could staff with live interpreters were a small fraction of what guests actually walked past. The audio tour was supposed to fill that gap.

The legacy product wasn’t doing it. The TourMate devices were “big and bulky — I equate them to a big 1980s cell phone.” To play a stop, guests had to type a prefix number followed by the stop number, carrying around a corresponding paper map to look up the right code at each location. The reviews were uniformly negative. We had no rights to edit or update the content. We had no way to handle the dozens of preservation interruptions a 300-year-old estate goes through each year. And it was a $7 add-on that wasn’t available to school groups — a third of our visitors. Adoption was in the single digits.

What we did

Picked a platform that put the content first

The replacement is the Podcatcher Pro from Guide ID, a Netherlands-based audio guide company whose product philosophy is “audio only” — no screen, no distractions, no scrolling. You point the device at a small tile (we fixed those to our existing interpretive signs); the device fires an infrared beam at the tile; and the audio for that stop starts. Three buttons: A, B, C. Volume, play/pause, volume.

Brought production fully in-house, podcast-style

The single biggest content shift was tone. The legacy tour was an institutional voice reading at you. The new tour is a conversational, podcast-style production — “like you’re going to Mount Vernon with your two best friends who happen to know a lot about the estate.”

Every stop has at least two layers:

• The A track — the main 1–3 minute biographical or story-driven narration. The life of an enslaved person who lived at Mansion House Farm, a battle from Washington’s wartime correspondence, a domestic scene from the Mansion.
• The C track — a curatorial highlight from a Mount Vernon expert who isn’t normally available for live interpretation. Architecture, archaeology, gardens, distillation.

The production model was deliberately scrappy:

• Scripting in-house, by Mount Vernon’s communications and curatorial teams.
• Narration outsourced via Fiverr — two main narrators we worked with frequently, plus 40+ supplementary voice actors for the secondary characters and scenes.
• On-site recording for Mount Vernon experts — curators, architectural historians, archaeologists came into a studio on the estate to record their C tracks.
• All editing done in-house. Mount Vernon owns every audio asset.
• Sound design. A scene in the empty slave quarters gets the ambient sound of an empty room and the imagined return of ten to twenty workers at sunset. The room itself starts to feel different.

Made it free, made it eligible to groups, raised admission

The pricing flip in 2020 changed everything. The audio tour came included with general admission for the first time — including school groups, which had been entirely excluded from the $7 add-on. The change was paired with an admission price increase. Adoption ramped immediately and kept ramping.

From Matt’s 2020 presentation on the program:

You can see in the chart where, in a normal year, we had a little bit of a pickup. But already this has ramped up — and the usage has greatly increased.

Matt presented the program (and lessons learned, including the COVID-era adaptations) at a 2020 industry session. Full 22-minute talk:

Five languages — designed for international visitors

Washington DC pulls international visitors year-round, and Mount Vernon’s share of those visitors is significant. The tour shipped in English first, then expanded to Spanish, French, Chinese, and Ukrainian — the Ukrainian-language version added after the 2022 invasion as a deliberate gesture to a wave of newly-arrived guests and refugees in the DC area.

The foreign-language versions deliberately move away from the podcast two-host structure to a single narrator with a simplified, context-rich script — non-American visitors often need a different layer of background to follow the founding-era narrative.

International-visitor support, beyond the tour itself

The audio-tour languages slot into a broader international-visitor program — translated maps, on-site signage, web translations, and partnerships with embassies and the regional tourism office. The audio device was the most visible piece of that program but not the only piece.

The killer feature: edit anything, any day

One of the biggest reasons to switch platforms was operational: with the legacy product, updating a stop meant calling the vendor and waiting weeks (and money). With Guide ID’s online content manager, we could edit and republish any stop the same afternoon. That changed what we could do as an institution:

Preservation tour stops, on the fly

When the Mansion or an outbuilding goes into preservation work — scaffolding up, doors closed, plaster off — the visitor experience used to take a real hit. With Guide ID, we deployed small green easels with a Podcatcher tile in front of active preservation sites. Guests scan, and they hear from the preservation team directly — an explainer about what’s happening, why, and how long it’ll take.

It’s not that our archaeology team or our historic preservation team doesn’t like talking with guests. But guests sometimes don’t want to bother those individuals — and they still want to know what’s going on.

The architecture director Thomas Reinhardt’s scaffolding-era explainer of the Mansion’s rustication technique (the way Washington’s carpenters made wood siding look like cut stone, by throwing sand onto wet paint) became one of the program’s most quoted tracks — available only while the scaffolding was up.

Editorial content updates as the scholarship evolves

The history of George Washington and the people enslaved at Mount Vernon isn’t static. Curatorial findings, scholarship on the enslaved community, archaeological evidence — all of it changes year over year. With editable content, the audio tour stays accurate without paying the vendor and reprinting maps.

Multi-phase rollout

Instead of waiting until every stop was perfect, we shipped phases. Phase 1 covered the historic area (the Mansion and the immediate grounds). Phase 2 added the working farm. Phase 3 was the museum and education center, deliberately held back because that space was being redone and the interpretation would change. Within Phase 2, even individual stops could ship as they were ready — four of seven stops live while the other three were still in production. Guests never noticed; the tour just got bigger over time.

COVID: the platform paid for itself

When the estate reopened during COVID, we expected the shared-device model to be a problem. It wasn’t. Guide ID released a “Bring Your Own Device” mode: each station got a QR code that opened a web version of the same audio. Mount Vernon packaged each device pickup in a sealed plastic bag with a sanitizing wipe and a printed QR code, and guests chose whichever experience they preferred. Pro-active visible cleaning of the devices made it work in practice. Most visitors still chose the physical device.

Take the tour home: the email recap

The Podcatcher Pro logs which stops each device visited during a tour. At the exit desk, guests can scan their device at a kiosk and enter their email, and Mount Vernon sends them a recap of the stops they visited — plus a teaser of the stops they didn’t reach.

That single workflow does three things at once: it’s a souvenir, it’s a reason to come back, and it’s a quiet first-party-data capture for the membership team. Many of those recap emails turn into membership renewals or pre-visit signups later.

What we learned

• The right pricing model is not the one that maximizes per-unit revenue. A $7 add-on left 90% of the audience without context. Free-with-admission cost a small line item and unlocked a much bigger institutional outcome.
• Editable content is a strategic capability, not a feature. Owning the content management gives an institution the ability to be timely, accurate, and responsive at the speed of the actual work happening on the grounds.
• Audio is the right medium for a 384-acre outdoor site. Visitors want to look at the place, not at a phone. A pocketable, audio-only device with no screen is exactly the right form factor for a walking estate tour.
• The conversational two-host format works. It out-performed the institutional “authoritative narrator” format on every signal we could measure: dwell time, completion rate, opt-in rate, and post-visit recall.

Why it mattered

The places we can staff with actual interpretation are a tiny fraction of the estate. The audio tour gives us the ability to interpret all of it — whether we have staff in a particular location or not.

An audio tour is the most leverage-y interpretive product a 384-acre historic site can ship. Done well, it makes every building, every garden, and every overlook into a curated experience without staffing every building, every garden, and every overlook. Done badly, it costs money, sits in a closet, and gets one-star reviews. The switch to Guide ID, the in-house podcast-style production, the free-with-admission distribution, and the editable content management were the four moves that turned the program from a single-digit add-on into Mount Vernon’s most agile interpretive layer.
