Pretty sure it is 4pm. You can check earlier and see if your room is ready tho. Plenty to do in walking distance tho if it is not.
It was always 4 pm unless they changed it, but they are good about if you request early ck in unless the are all booked up. You can always hang out at the beach accross the street, get something to eat at one of the restaurants, or walk around the area if not.
