Ok we are going June 15 to June 21. We are staying at HRH, so we get the unlimited express passes. The problem is Volcano Bay. My daughter isnt wild about it (14 my wife says body issues), my son thinks its a great idea (12 yrs), my wife not pleased about being in a swimsuit all day LOL. Me I dont care I am 50 and yeah I have dad bod as my daughter puts it. So rather than do the 3 park ticket for the duration we were thinking of just getting a 1 day ticket for Volcano Bay, and staying with the 2 park ticket. Is this doable or are single day tickets for a certain day? Should we just buy the ticket at the resort the day we want to go? I understand that Express passes dont work at Volcano Bay. Where the only thing they wont work at UO or IA is the New Hagrid Coaster. Please experts give me some advice.
