Another option might be a gym. Although I just pass by and wave at my husband on the way to the beach, he does use the gym at Divi every day. Maybe there is a gym where you are staying? A few of us prefer just a morning walk on our beach. It’s about a half a mile, and we do the loop a few times but stay on the property. After a full day at the beach, none of us would be ready for any serious activity. Stay safe as others have suggested and look for other alternatives.
