When we were at CBR earlier this month, the CBR buses were at either # 5 or #6 at each place, including DD. That doesn't mean it was the fifth or sixth "shelter", because more than one stop uses the same overhangs, etc. The driver did say a couple times to check the name on the bus as to where it's going because of different buses parking near the same area. It was never the furthest away, usually about the middle if they were strung out like at Epcot or MK.
They run frequently and if the driver sees people walking toward the stop, he/she usually will wait to see where they are headed, unless the bus is already totally full.
