I would highly recommend doing nothing for a day and just enjoy the sun, the sights and the beauty of the ocean all around you! The Hyatt is a great place to lay on the beach and soak up the rays. Also, walk right across the street from the Hyatt and enjoy a meal from Hostarios the Italian restaurant. In the 10 years we have been going to Aruba we have never had a bad meal or service there. Have a Bushwacker at the outside bar at the Hyatt!! Enjoy your stay - Aruba is the only place that we return to every year - the people and the ambiance are tremendous!
