There are also the inconsiderate guests who don't think the 11AM check out time applies to them. Or they leave a total disaster in the room they are vacating that takes a lot longer and more staff to clean than it is supposed to take. Both of these situations could cause your room being ready later than usual. We are DVC and one time we weren't able to get into our villa until almost 6PM. Both of the situations I mentioned took place in this case. It was New Year's Day, they had had a big party the night before and decided they didn't want to leave at 11. When they finally got them out of the villa around 4:30, it took a staff of five to clean up the mess left behind.
