Oh you should have a great time. This is the best time to go. We went 4 times last year (season pass). I would advise that you take a light stroller and put a scarf on it so you can spot it easily when you come out of a show. Though I don't expect the crowds to be that bad now. Also it's a good idea to take a big bag, like a beach bag so you can throw all of your valuables in it and take it in with you to see a show. You could also take some food/drinks with you and save some money, because the food can be pricey inside. They do not allow food/drinks inside and really don't have a place to eat outside of the park "( but since it's not at all hot you could eat in the car if needed (?)
They did let us take in sippy cups and my husband took a few of those crust less peanut butter and jelly sandwiches in his cargo shorts that the kids ate. I would advise that you do pack clothes for all seasons. We went in April and actually left the park because of freezing rain! Texas weather, you never know! Also when entering the park, I would start in the opposite direction as the crowd. In other words, go in backwards. The park is mainly a big circle. That away you can avoid crowds.
As for saving $, get you tickets online. Maybe get some sea world kind of gifts for the kiddos before going to the park.
Hope you have a great time,
