We've stayed there twice. You guys are going to love it.
Anyhow, the first time, our room was right off the lobby on the 6th or 7th floor above the Whispering Canyon Cafe. That was nice but I am a light sleeper and sometimes the servers in the WCC would get pretty loud and wake me up in the morning.
The second time, we stayed in the wing across the pool from Artist Point and had a pool view. The room was pretty much the same, but it was quieter in that wing since we were away from the hustle and bustle of the lobby. Also, from our balcony, we could see the Electrical Water Pageant go by at night.
All in all though, the WL is a pretty compact resort. No matter what room you end up in, you won't be very far from the restaurants, lobby, bus stop etc. Plus, it is all indoors (except for the bus stop of course.)
