Hello! I was checking the discount for Discovery Cove with a Sea World Annual pass, but if there are 4 of us (say all adult prices) that buy a Seaworld annual pass to get the discounted Discovery Cove tickets, which are $69 (no dolphin swim) it comes out to $752 which is more than just buying regular Discovery Cove Tickets! How is this supposed to save money? Did I do something wrong, or do you just need one Seaworld pass to get the discount rate for everyone? Thanks!
