We do this all the time! It's quiet easy! We tell the bellhop the night before that we are switching to another resort the next day and need their services in the morning. They come to the room the day we transfer, tag the luggage for the hotel we're staying at next, and we don't touch it until we're in the next hotel. We go to the next hotel and check in, if our room isn't ready yet, they give us a number to call during the day and we periodically call to see if the room is available yet. The only catch with this is that you may not see your luggage until after 3pm that day, so they advise you to take whatever you will need for that day with you (park passes, if you plan on swimming - bathing suits). Just remember, you are not guaranteed the next room until check-in time which is usually around 3pm, so even if you have a car and drive the luggage over there yourself, you will either have to leave it in your car until your room is available, or leave it with bell services anyway.
