The stuffy, dark line for Pirates of the Caribbean. Yes, really.
Any time I'm in that queue, I'm back to being an easily-spooked kid trying to prep herself for her first Disney ride.
Pirates is also my only vivid memory of doing a Disney attraction with both parents while my mom was alive, so -- despite all the other more interactive, better themed and climate-controlled queues out there -- those old chess-playin' skeletons will probably be #1 in my heart forever!
