When we stayed a few weeks ago, our schedule got messed up when we had to change rooms - when I called housekeeping, she said guests could call and change any dates they wished as long as we asked, something about a new system they have. So if you needed housekeeping a day sooner, just call and ask, or if you don't want to be bothered until another day, just call and change it. We loved not being bothered every morning, and I don't mind throwing a few towels in the laundry if we needed some clean ones. Enjoy your trip!
