Hi all, first post in a long time. We're thinking about doing a cruise and then buy a one day ticket for Universal in October. We're also going to add on HHN to our ticket. My question is if we go to IOA for the day, I assume we would have to wait until the US side opens to the general public before we can get in for HHN? Also are we allowed to do any rides on the US side once were in the HHN event?
