Either we were just lucky or the transportation has gotten much much better because we didn't wait a single time (for a boat or bus) for more than 2 or 3 minutes. One thing that has changed since September is that the Wilderness Lodge busses now go to Fort Wilderness too, instead of to the Polynesian and Grand Floridian. We did find that the path the drivers took was a little eratic, as we would sometimes stop at FW on our way to the parks, and then again on the way home. But other times, we went from the WL to the parks and then on the way home stopped at the WL first! I do wish they would keep it consistant... But other than that, the transportation was outstanding!
As far as room noise, we could hear a little bit from the Whispering Canyon, but we rather enjoyed that. It wasn't loud, and you could certainly sleep through it, but in the evening, it was fun to hear. I remember at Christmas time we could hear carolers from the lobby and that was delightful! The WCC closes at 10PM, so that wasn't a problem for us!
Roaring forks is great... we never ate there, but never saw a line when we were refilling our mugs either.
The pool was fine. Not terribly crowded, but not uncrowded either... In the afternoons they have a duck race for the kids on the upper part of the creek running from the lobby... too much fun! We have no kids, but it was fun to watch!
