Ticket question

[katyringo]

We have 2 park 1 day tickets for our October trip. They are date based for 10/21. We also purchased express passes for this day.

we are also doing Disney world for 3 days.

does universal allow you to change the date of your ticket/express pass?

I only ask because if the new park reservation system at Disneyworld. When we book our three days for Disneyworld I’m worried a park won’t be available 1 day but we could get it for our universal day. Hopefully I’m over worrying..
