In the off season, it is usually no problem getting into your room when you check in, although we stayed at the WL in the off season in 2000, and we still couldn't get into the room until 3 pm. Since you are going in the middle of the summer, however, the chances of you getting in at 11 am greatly decrease. Just precheck in, get your resort pass, and the phone number, and periodically check back with the front desk, via phone to see if your room is available. It is no problem at all to precheck your luggage, and when you arrive at 3 pm, then have the valet bring it up. You should be able to get into your room, at the latest, 3:30, which should give you plenty of time to freshen up before dinner.
