According to this article "Bus service for Disney's Pop Century, Disney's Riviera Resort, Caribbean Beach Resort, and the Art of Animation Resort will now depart to and from EPCOT and Disney's Hollywood Studios only once per hour."
Once per hour!?! Oh I do not like this, not that Disney cares what I like, but this absolutely changes my mind about staying at any of these resorts. I might be fussy about every half hour, but would still stay, however once an hour really takes extra planning. This is now a huge "do not stay here" recommendation from me for guests with fear of heights.
