Average hotel occupancy hovers around 60-65%. Think about what that means for a hotel with 100 rooms.
- 35 rooms are empty from the night before. Dozens of guests could arrive at 9am and immediately be given a room.
- Only 30 vacated rooms need to be cleaned to accommodate everyone. The 35 holdover rooms from the night before plus 30 more that are turned-over will get you to the 65 needed for the new day.
- 35 rooms don't have to be cleaned by any specific time because they aren't needed.
Disney hotels typically operate around 90% occupancy.
DVC resorts are effectively 100%. Barring an unbooked room or no-show, every single vacated DVC villa must be turned over by 4pm. If you have 300 guests checking out, 300 rooms have to be cleaned by 4pm.
Disney should operate with that standard in mind. But any variety of factors conspire against them on a daily basis: employee sick calls, no-shows, rooms that are left in particular disrepair by departing guests, rooms that need maintenance attention, etc.
Plan for the worst and hope for the best. Years ago we gave up on things like 6am flights and arrival-day ADRs because there's too much uncertainty. It's less about giving Disney a free pass for bad performance, and more about acknowledging the things that can go wrong, and not putting myself in a position where they will cause our trip to begin with anger and frustration.
Do I believe that some exhorbitant number like 25-50% of all arrivals are getting their rooms after 4pm? No, absolutely not. But there's always a chance I'll be the one who gets hit. I'll report the problem to management. But I'm not going to let it damage the start of my trip, I'm not going to unload on some poor desk clerk, and I'm not going to assume that dozens of others are suffering the same fate due to widespread managerial incompetence.
