According to the floor plans I've seen in threads like this one

it appears that there are two closets in the one bedroom, and neither of them are huge. One is just inside the front door, and the other is just inside the master bedroom door. I've been used to the big walk in closets at the other DVC resorts in the one bedrooms, primarily for storing the luggage, so I'll be interested to see for myself how large they are.
I echo the plan to pack less and plan to do laundry. They provide Tide laundry detergent (a one load box per day if you have a cash reservation) so I usually just pack a box of dryer sheets. I take enough clothes for about four days, and do laundry either in the evening or when I'm getting ready to go out in the morning.
