I noticed that this is your second thread about Trapp. I've been off-line for a while, so I will respond to this question and also go on about the resort for a few minutes. We own at Trapp too. Our family really enjoys the peaceful natural beauty of the resort and the village.
You have listed the major tourist attractions. There is also a cider mill close to Ben and Jerry's, on the opposite side of the street, that was rated by Gourmet Magazine as having one of the country's top-10 donuts. Our family likes to walk around Stowe. The little library is very nice. Your kids might like story time. There are some nice restaurants and shops.
For more TFL info, go to
www.trappfamily.com, click onto activities and, on the left side of the page, click on this weeks activities. This listing changes seasonally, but you can get a pretty good idea of what to expect. Trapp is a world-class cross country ski center and the resort is close to downhill skiing and snowboarding at Mt. Mansfield.
You could also just go sledding right out in front of the even-numbered timeshare units (they are built on a hill), and, when the kids are done, have some tea or hot chocolate in front of the unit's large wood-burning fire place- maybe even have some pasteries that you purchased earlier in the day at the bake shop (under the Austrian Tea Room) (check for hours). Then a nice family swim in the beautiful indoor pool.
Any other questions, just ask.
