We have the SeaWorld/Aquatica combo AP for each member of our family

. Parking is free at both parks with this dual-park annual pass.
OP, Aquatica is an awesome waterpark......we like it better than the Disney ones! Check out the Aquatica photo sticky at the top of this forum if you want to peruse some photos of the park. Its bright, colourful, and so much fun. Roa's Rapids, the tubeless (not-so-lazy) river with a fun, swift current is the best waterpark attraction anywhere, and something that the whole family can enjoy together!
