hello, my family (daughter 14, daughter 16, wife) is going to US/IOA staying at the hh this august for 4 nites, then off to the beach club for 7 nights. We are Disney veterans but hav'nt been to universal or seaworld in almost 20 years. here is my question........ right now i have tickets for one day at seaworld and 3 days park-park for universal. we arrive early on a Wednesday and transfer to Disney on Sunday. that gives us 2 3/4 days at US/IOA and the one day at Disney. Should I add (for fairly short $$) a 4th day to my US tickets?? How long will it take us to tour Seaworld? I am thinking if Seaworld is a fairly short day (there at open, tour to 4 or 5?) we may want to go to US/IOA in the evening. any info would be appreciated!!
