hmmm. having stuff polluted or closed would be a bummer. No need for theme parks, we will have gone to WDW a few weeks earlier. Teens like hiking in mtns, thru woods, waterfalls, WW rafting, creeking. Looking for a solid 5 day place with good mountain experience to add to 2 days in Boston. I posted similar q this summer about Conway/Lincoln when we were going to Acadia. But, if we drive, it would just be to Boston and then to a TS for 5-6 days, and Berkshires is somewhat on the way. Plus, friends said they would not go to Conway area for vacation.
Our other option is a NE/Canada cruise on RCCL. If anyone has an opinion on whether to just take the cruise, please chime in. Difference is $5K for cruise vs. TS stay. We have cruised before--it would be more of a floating hotel, than a "wow, we're on a cruise" experience. DH would not have to drive and we would have unlimited food, etc. But, cooking is really not a big deal for us. We would eat out for dinner a few nights in the TS and Boston.
