My 4 yr old really enjoyed the dioramas here, mainly the caribou hunt and village life scene. The wolves, giant beaver and mastodon was also appreciated. The museum has a lot to see, but those are the big highlights for the pre-school set. They also have an observation tower that was kind of fun for a pre-schooler but I don't know why they bothered with it, as it just overlooks some scrubby CT countryside of no note. I have to take a star off b/c the admission price for an adult was $20 (hey, maybe skip the useless observation tower and charge less for admission), there was no bathroom on the first floor where you enter (major design flaw) and the dining facilities were closed when we visited. Instead we popped over to the Foxwoods Casino for a bite. The Casino facility itself is dated and worn, and unfortunately has the sad and depressed air of a lot of these type of casinos. I didn't want to take my small children there but there weren't many other options close by.
