We are going to Universal for one day in November. We were planning on doing IOA, so just were going to purchase a 1day/1 park ticket, but what I was wondering , depending on how quick the day goes if we wanted to go to US the same day ( say later in the afternoon) will they let us upgrade our ticket the same day? Dont want to buy a 2park/1 day ticket ahead of time if we are not going to use it.If so how much for the upgrade on the same day?
thanks, Lauren
