I rode Goofy's Barnstormer 7 times in a row with the kiddies one quiet January morning. I couldn't handle any more, so we got off and their dad and grandpa got on with them and did it five more times in a row for a total of 12 times with only one off/on. I was ready to hurl.
My mom and I did the Teacups with the kids three times in a row without getting off that same day. Let me tell you how much fun THAT was.
At the end, we didn't need to get off because of other guests, but if I didn't I was seriously going to hurl. The kids had that thing whipping!
And lets see...we've done the carousel again and again. DS and DH did BTMRR three or four times in a row. We've done EE back-to-back, but that isn't something I'd repeat. DS was not happy about the second time!
We've also been offered a return trip on IASW (but seriously, who can take that more than once?!) and we've had a few other rides where we've gone twice in a row without exiting. POTC was one, but not this last trip - it was down a LOT.
Oh, and I know, I know! What is the thing in the Epcot ball?! The kids and DH did that one over and over and over and over and over...repeat until you can't stand it any more. We had the best video postcards from that one though, because they kept making different faces each time and I stayed downstairs and watched for their pictures. LOL!
