Where can I find the best price?

Title. 2 people, 2 days, that’s all we need. Trying to find tickets has made it seem that despite only going for 2 days, I need to reserve 7 days that I COULD show up on, which seems like a pretty massive waste of money given I know when I’ll be there. Is this just how the place makes more money? Does it make more sense to just buy an annual pass? Thanks
