1. The two views are courtyard or villas pool. A high floor, courtyard view gives you a chance at a fireworks view. A room close to Bay Lake could have a nice water view. A courtyard view room will most likely be noisier than a villas pool view.
2. There are two refill stations, Roaring Forks and Geyser Point quick service.
3. There is a bus from WL to FW that is really quick and drops you off close to Pioneer Hall.
Take time to tour the two buildings. There are lots of interesting things to see. There is also an architectural at 9 am M-F that is interesting.
