Self parking is actually very close. You can drive up to the resort and unload your luggage and leave it with a member of your party (wife and kids), drive across the street and park, and walk back within the space of a couple of minutes. If for some reason you are the only one in the car, or you want to keep your family with you and have them walk back to the hotel with you, then you drive up to the hotel entrance, a bellman will store your luggage, give you a claim tag and you can go on your way.
Even if we self park, we almost always leave our luggage with a bellman.
Have a fun trip!
Enjoy life and great vacations!
