You can get tickets online or in person! Look at and feed alligators. This is an activity that takes about 2.5 to 3 hours, depending on how much you want to stop and look at each exhibit. They also have a petting zoo (pictured)
Axe throwing, go carts (they are very fun, we've tried it), mini-golf, an arcade, and bowling! Wear closed toe shoes and something comfortable. You can really kill some time here.
Fun to walk around for a couple of hours, look at stuff, solve puzzles. We went to a wedding expo here and it was fun.
