M.B.
The ICE exhibit at the Gaylord hotel in Grapevine should be worth a visit. You would want to buy tickets in advance as I imagine Thanksgiving weekend would be really busy. We went to the one in Florida a few years ago and it's really "cool" - something folks of all ages will enjoy. Also the Gaylord Riverwalk themed restaurant has a nice breakfast buffet (not cheap, but has tons of food choices to suit ANY diet).
