Definitely Buzz Lightyear in any of the rooms! It's one of my favorite rides! I'd try and get the Galactic Hero title while being stuck!
Pirates of the Caribbean just at the point of hearing "Dead Men tell no tales".
Haunted Mansion is my favorite ride but I would rather be stuck in the attic with the ghost bride and watch all her husbands change. Oh man...I would hate to be stuck in the graveyard with the ghosts that pop up from behind the graves! I am 25 years old but I STILL look away from the pop up ghosts every time! They are freaky!
