My parents recently moved to the Tampa area (Hudson) and we will be visiting for the first time in a few weeks (it will just be me and my 4 & 6yo). We have 3 full days and aren't going to WDW. I know Sea World isn't far. Any other recommendations for things to do with the kids? Doesn't have to be theme park and I'd like some ideas that aren't all-day things since we may visit with some relatives, etc.
TIA!
