We are going to WDW from Feb 1-11. On Feb 3 Dh and I are attending a trade show in Tampa while Grandma and Grandpa hang out with the kids, DD9and DD2.5.What can the 4 of them do (in Tampa) while we go through the trade show (4 hours, give or take). They will have a vehicle as they are dropping us off at the Convention Centre. We have also never been to Tampa. Thanks for any tips!
