We are planning on buying 7-day tickets, but only spend 4 days in the parks. I know we will have to get the no expiration option. I was just wondering if we have to pay $55 because it's a 7-day ticket or do you pay according to how many days are left? In our case, it was be $10 a ticket for 3 days left. I am pretty sure we will have to pay $55 a ticket, but $10 would be a lot better.
