I've stayed at POP, ASMU, and ASMO. If you haven't stayed at the AS resorts try them. The theming is different, which makes it interesting to me. Also, like was previously said, I have had to share a bus once with the other AS resorts. It was one afternoon I left DHS early to go back to my room. This is the only time in my previous stays I have had this happen. If you go to the parks at opening or closing you should not have to worry about sharing a bus. I would say try something new, try one of the AS resorts this time.
