DVC studio units have real coffee mugs and a modest supply of paper products otherwise.
Based on our recent stay at SSR:
Housekeeping visited daily, just to take out trash & recycling. On day 4, they changed out towels. You could not make pool reservations in advance. The 2 "quiet" pools were first come, first serve and heavily utilized midday. If people tried to reserve seats but no one used them for a good while, others moved the items and used the seats anyway. As the 2 "feature" pools filled to capacity on hot days, CMs took arriving guests' names and cell phone number for a waitlist. We were text messaged when space was available and our seats (either 2 loungers or 1 table/4 chairs) were held for 15 minutes before moving down the waitlist. Most people didn't wait in line in the heat but returned when texted. Pool towels are plentiful, provided poolside at all 4 pools.
