We always check in as soon as we get there. Leave the bags at the front, they will take them to your room. They have always given us the keys to our room, with the understanding that they won't be activated until 4:00. But we can hit the parks and when we return, we don't have to stop at the front desk. We just go to our room, open the door, and wha-la, lugguge is sitting there waiting to be unpacked. So far we haven't been able to talk the CM's into unpacking for us!
