And just to note: the boats aren't just one way - they will circle around between the campground, Wilderness Lodge, and Contemporary, with one boat going in each direction (Camp, Wilderness, Contemporary, Camp - and Camp, Contemporary, Wilderness, Camp). I've been known to leave Wilderness heading to the campground but hopping on the boat going to Contemporary first, just to take the longer boat ride as I find the boats so relaxing and scenic.
I never use the bus to get to Wilderness Lodge - but I also never go over there before 3pm so it works out.
BTW - long ago when Wilderness Lodge first opened, the long path that runs between the campground and the lodge used to be open to golf carts...you could take your cart all the way down to the Wilderness Lodge end - park in a little cul-de-sac and walk up to the Lodge. It was about 100 feet past where the Wilderness bus stop is. We always carted over to the lodge for lunches, dinners, bar visits, etc. and was so nice to have our cart waiting to ride back to the campground. I miss those days!
