You can park your car in the front, and leave your luggage in it until you find out where you room is when you check in. You could then move your car to the parking area closest to your room and unload your luggage.
Value resorts have limited bell services. You could leave your luggage with them, but it could take them up to an hour to bring it to your room.
If you arrive and your room is not ready yet, you can leave your luggage with bell services and then go to the parks. When you return, your luggage may or may not be in your room - you may need to retrieve it from bell services, or call and have them deliver it.
