Picked up our tickets yesterday at the USF will-call kiosk with no line and no problems (3 FFP+Express, First 3 Saturday Pass, 1 Saturday Express Pass all AP discounts)
Other tidbits I have ran into from trying to buy passes online and over the phone.
You can NOT cancel a UTH pass day of, sounded like can't be cancelled at all.
The website has express passes mislabeled at least for AP holders. Make sure to check all the drop downs and see if you can select the calendar day after wards. The first Saturday Express Pass is listed in the first option of the drop down but the date cannot be selected. You have to select the second option of the drop down in order to be able to select the date.
Be careful buying AP discounted passes over the phone. It seems there may still be a lot of confusion as to what discounts are what, how much they are, and where you can get them. Tried to buy the first Saturday pass and was told it was $76, after going back and forth a few times about how there are no passes less than $70 (and he had been selling these to people for several weeks), I realized that it was because the AP discount passes have different names. The one we bought being "HHN AP 1ST 3 Weekends Sat".
The rep I spoke to was super friendly and super helpful but please make sure that you know what you are buying and triple check it all because there still seems to be a bit of confusion.
