A lot will depend on whether or not your room is ready for you. If it is, then luggage assistence people can take it to your room for you. We generally tip $2 per bag when they get to the room.
If your room isn't ready, you can leave it with the luggage assistence people and then give them a call when you are able to get into your room, later in the day. Again...a few bucks per bag when they are delivered is the norm.
Another question...how are you arriving at the resort? If you are arriving on DME, no tipping is involved if you have tagged your checked bags.
