I'll bet this has been discussed before at some point, but for what it's worth-- we don't really like daily Mousekeeping service (or daily cleaning services at any hotel). I don't like worrying about when I'm supposed to be out of the room so that I'm not in their way, don't like worrying about picking up after the kids every day so that the room is cleanable condition, etc. It just feels like a big intrusion. The standard amount of cleaning, trash/towel, etc. in a normal
DVC stay is just perfect for us.
It's especially true on longer vacations! One time we took a wonderful 12 day trip to Maui (my wife was writing a book on that trip, very relaxing) and the biggest complaint I can offer about the trip was the constant presence of very helpful and friendly, but intrusive, housekeeping staffers.
