It's much cheaper than buying tickets on-site, and you don't need to collect tickets; you can just scan a code to enter. The experience is still quite impressive; several of the flight experiences are comparable to Universal Studios and Disneyland, but the wait times are much shorter. I drove there, and there was plenty of parking right at the park entrance. After the park closed, the nearby restaurants were quite crowded, but the ambiance was nice, with a sea view.
