Boat launch only goes to Fort Wilderness and Wilderness Lodge---you're staying on a Monorail Hotel!!!! You take the monorail to Epcot and the MK or the Poly or Grand Floridian. You can take busses to AK, MGM, DtD, and the water parks. You can take the monorail to the TTC if you need to hop to a different hotel.
As far as the wing rooms go, we didn't have any major complaints. The rooms are very spacious and are decorated the same as the tower rooms. However, the N. Garden Wing's hallways and common areas seemed a bit dingy. I think Disney let things go a bit while Shades of Green guests stayed there, which is too bad. I only say that cause I went twice last year- in March and then again in October. There was a HUGE difference in visual cleanliness to me....scuff marks all over the hallways, an Exit sign hanging by a wire the whole week we were there, room service trays sitting in the hallway ALL day....in March we didn't notice this at all...in October it was pretty bad but not horrific. And like I said, the rooms themselves were very clean.
