As soon as you arrive, you are free to use the facilities. Pack a swim suit in your carry-on in case your room isn't ready. You can leave your bags at the front desk and then head off to explore and enjoy the sunshine. Grab a bite to eat and your room just might be ready after that.
Also, are you arriving in Montego Bay at 11am? If so, you won't be at the resort until 1pm at the earliest. Be sure and pack snacks in your carry-on as there isn't anything to eat at the airport.
