With more than 30,000 hotel rooms across the resort, Disney World's washing machines see a lot of laundry. In an effort to cut back on water usage, Disney has made it easy for you to reuse your bath towels. Just hang your towel up after using it to signal to housekeeping that you plan to reuse it. Towels left on the floor will be whisked away to what may just be the world's largest laundry room.
