As said above, it depends on how busy the resort was the day before your arrival. If all rooms were occupied the night before, the first clean available rooms will probably not be available until noon or later. Guests must check out and then housekeeping gets the first rooms ready. If the resort had a lot of vacant rooms the night before, you could probably get a clean ready room by 7:00 am. They will assign the first ready rooms to people who have done online checkin and specified an early arrival. Online arrivals get the first precedence for ready rooms. As the other poster stated, if you are very picky about building or other room atributes, it may be later than if you are willing to take any room in your category.
