Used both last month.
MCO to Pop: Sunshine Flyer
Picked up luggage, and went to the check in desk on level 1. Waited for our hotel to get called, and then our luggage was loaded onto the bus. Cartoons were playing (non Disney), and train themed trivia would appear on the screens. Bus driver also asked us some Disney trivia questions. First dropped off guests at All Star Movies, then went to Pop.
Pop to MCO: Mears
Pick up was where the magical express used to pick up from. Driver loaded luggage into the bus. No cartoons playing, but the radio was on. Dropped off one passenger at Terminal C before the rest of us were dropped at Terminal B
