We like Celebration and almost always stop by during our Orlando vacations. And we really like the Celebration Town Tavern - it's basically a Massachusetts/New England themed restaurant with great seafood and lots of other food choices. If it's warm enough, the "Boston Garden" outdoors section will be open for dining (they have heaters for coolish times). Grab one of the tables with the swing seating for a nice experience.
What's to do in Celebration?
Well, Celebration isn't a traditional tourist attraction it's a community so it has a lot of the features that you'd find in any town. But some of the things to do include...
a few shops that are interesting,
several eating places,
a movie theater, and
great walking paths - look for the wildlife, including some gators.
I think that you can still rent one of those electric vehicles or a Segway to scoot around the town (or you can just walk or drive around) and see the various Celebration homes. Look for the unique little "for sale" signs that are posted in front of some of the homes.
