I think that free upgrades from standard to woods view and from woods view to courtyard are fairly common, since there are so many more courtyard view rooms than the other two types. A courtyard view room costs about $10 more per night than a woods view, and a club level room costs about $75 to $100 more per night, but that will vary by season. I don't know if you'll be able to upgrade your room type upon arrival.
Yes, there are laundry facilities located near the elevators and Roaring Forks.
The boats are very easy to use, coming about every twenty minutes. There is one boat that is direct to MK and another boat that travels between the WL, the Contemporary and Fort Wilderness. We really like using the boats.
The bus to MK takes about five minutes and is very convenient. The buses to the other parks is a little less convenient since they share with other resorts. But WL is the first stop on the way back from the parks.
