Hmm, what is my least/most favorite queue...Good topic.I would say the worst queue is the one to Stitch.... because of what's at the end of that queue
Seriously, as far as waiting for something that I want to see/do, my least favorite waiting area has to be for Philharmagic. Just unpleasant & crowded (speaking of the waiting area, not the neat 'ads' in the switchback area)...
From least to most favorite, here are my 3:
3) Least favorite - BLRS: the queue just feels dirty, like the air is musty
2) Tolerable - IASW: I enjoy seeing the clock animation and I like seeing all of the sparkly objects (I am a sucker for glitter)
1.5) Honorable Mention - HM: Favorite ride and the interactive queue is interesting
My number 1 queue is and probably always will be SM. I love the background music, the pictures, lighting, etc.
