No . But you can fill out the waiver form online.
Sometimes they have passes online I think I heard they also have them at Costco. Groupon has has a some tickets for sale at a discounted rate. You cannot buy it they don't have any online for themselves to sell you, but I think you can buy them when you get there and fill out the registration form that they want you to fill out.
You can buy passes through Groupon.
