Let me preface my post by saying that I really, really enjoy both UO parks.
Then let me say that the last time I spent more than one day there was when ROTM opened up.
About two years ago me and the GF were staying at the polynesian and since she's a travel agent she gets comp tickets to UO, so we got a towncar to take us over there at about 9 or 10. Started at USF since it opened first, rode MIB like 3/4 times, BTTF, ROTM 2/3 times,watched some ROTM CM's scare guests on the way out of the gift shop near the lockers(It was a great time) Jaws, saw T23D, almost got ran over by Doc Brown
, rode ET, saw the Van Hellsing display and makeup show, then rolled out to IOA.
This was maybe 1pm, 2pm tops.
Over at IOA I made a beeline for the Marvel section, and we rode everything but storm force a few times, and got lunch at the baxter building. Dudley was down for refurb, and we didn't have a change of clothes so skipped Popeye, rode jurassic park once, went over to lost continent grabbed a snack at the enchanted oak, saw sinbad, did the poseidon adventure and rode DD at least twice. Went to Seuss landing, got some Goose Juice, rode cat in the hat and 1 Fish 2 Fish, went back to USF watched Shrek and got back to the Poly by like 7.
So, in 11 hours we did everything we needed to do there. Sure, we could have spaced it out took our time and maybe spend 2/3 days but 7 would be a bit much.
Also, as soon as we got back to our room we figured we'd take a nap then go to the Comedy Warehouse....
We woke up at 6 the next morning, lol.
