They are also sold through Central Forida Tickets and Travel, which is where I bought mine. You do not get a bonus water park pass however, but if you are short on time, you wont be able to use them anyway. They are cheaper ($155 for adults) + 7.00 shipping for your entire order.
I was very pleased with them. I ordered and received my tickets within 3 days, and the ticket agent Kelly was very nice and helpful.
You do have to call them, as these tickets are not listed online. The number is: (407) 932-2080
