Sorry, we're coming down to the wire (leaving Wed morning) and I realize I still have questions. UT has a 4 day plus one free ticket. We need five days and may upgrade to seasonal but we would have to do it on the fifth day because we would like to see Mannheim Steamroller on the fourth night. Will the fact that we are on the "free" day prevent us from upgrading the ticket on the fifth day? Also, the e-tickets come almost immediately, right? I don't have to worry that it's too late to order from someone other than universal, do I?
