Check out the first page of this thread for the resort map. There are 3 resorts, Yacht Club, Beach Club and Beach Club Villas. I'm not sure if there is inside access between BCV and BC, but you can definitely access all of the BC and YC indoors/undercover, including the restaurants and lobbies.
Not sure if the laundry access is inside or out, but here is the info from the front page:
Laundry Information
Self-service laundry rooms are located near the BC quiet pool and near the YC quiet pool. Another small laundry room may be found on the first floor of the YC, near the side exit (wedding gazebo side).
Washers are High Efficiency machines.
Both washers and dryers cost $2.00. Washers run for about 30 minutes. The sign in the laundry room says the dryers run for 20. Users have reported the dryers run for up to 30 minutes on regular and permanent press cycles.
Here's a photo of the ham and egg croissant. I can't remember how hot it was, but it was yummy. I have also included a picture of the make your own parfait station:
