We've done laundry every trip. Cuts back on what we need to haul with. When the kids were younger, our trips were during Spring Breaks~a busy time, but never had trouble getting machines. A laundry room is located by each quiet pool, so it makes it easy to toss in a load and take a dip. Or, just run back and forth from your room. The laundry is open 24/7~you need your room key to access it in the wee hours. Just bring your own laundry supplies (I like the Purex sheets), but used to "baggie" the powdered stuff, and bring dryer sheets. Don't forget the stain stick!)
