Adding a Day to a Ticket?

[branfam]

I just added a 4th day to 3 day park hopper with genie plus tickets this past weekend. It cost me $104 per ticket for the change. I called to do so as I paid for 6 people on 3 reservations (family trip). It took awhile to work through all 3. Just a warning. Keep an eye on park reservations. 5 of the 6 of use had random cancellations of existing reservations. Luckily I was able to rebook everyone without calling again.
