I booked a package today using a PIN and I only booked the 1 day tickets that were required. I was planning on upgrading to length of stay after I pay the balance off. This give me a little more time to save up! 5 of us will be travelling together. I know that we all have to be on the same package but I wonder how that affects ticket upgrades. I was wondering if it is possible to upgrade 3 of the tickets for the length of our stay. Can I do that once I arrive, or is that wrong? I don't want to break any rules. If this is possible, it would be prefect for our group as at least one person is planning on going to the parks for one or two days. If not, we will upgrade all 5 and move on! Thanks!
