The bus from WL does not go to the Contemporary Resort (CR) -- no resort to resort buses.
I also assume it doesn't go to the Ticket & Transportation Center - I don't know why it would, but I could be wrong on that.
The resort bus would go direct to the Magic Kingdom entrance, not the TTC. And for the other parks, it would go directly to those.
(there is however a boat that goes from WL to CR - with a stop at Ft. Wilderness, and a different boat that goes from WL to MK).
