I have a work and personal relationship with the Owners of Harvest Inn in Napa Valley (on Route 29 near St. Helena). I could work on accommodations for next year. Coincidentally the one owner is a car collector himself.
The only issue I see with accommodations in Napa Valley (at any location) is timing. A tour d’hoe event in September is during “harvest or crush” season, which also is the valley’s peak season in terms of accommodation rates. A room that rents for $150/night in May could easily be $800-$950/night in September.
There are a number of winery owners in Napa Valley that are auto collectors themselves, and would love to have a grouping of our cars in their winery.
I would be very open to hoping on the planning board for next year’s event
