From the resorts to PC they are currently using buses operated by another company, Academy or something like that? They are plain outside, but once you get inside, you honestly can't tell they aren't wrapped. They're just as nice and seemed exactly the same. Buses from the airport are currently operated by Mears and have the
DCL wrap on the outside. Now, on the way BACK from the port to a WDW resort we were in a Mears bus with the wrap. It seems they are only using the Academy buses from WDW to PC but not in any other direction.
I was actually on the bus next to a DCL transportation CM (she basically got everyone on the bus then sat down with her family and changed out of her DCL shirt into a matching t-shirt with her family to get on the cruise). She said stuff with Mears is a hot mess and it's possible the whole thing is going to go south any day now and all the buses will be operated by the new company. Again, I think they are called Academy or something like that? It starts with an A. Anyway, she said that actually, the new people are way easier to work with and she's been much happier in her role since she hasn't had to deal with Mears as much.
