We just upgraded four of the UT 2 day +1 free park to park tickets to seasonal passes. They charged us $10.65 each. They only needed the adults present (asked for an ID for each of us). We upgraded at the end of our park days as July was blacked out. Friends of ours upgraded five of these tickets a day later and paid the same $10.65 to upgrade. It would have been nice to get a refund, but I'm ok with only paying $44 to upgrade all of us.
I assume when you (and others) talk about your tickets, these are 2-park tickets based on the price. I was looking at 3-park tickets where the exchange economics seem to change quite a bit.
Also, we're going in September. Is there any benefit to ordering now vs waiting a couple months?
