We loved Aruba Ocean Club! It's a great place for adults. Great room service, close to great dining. Concierge folks were wonderful and helpful.
If you're looking for a great place for kids, check out the Aruba Surf Club!
If you're looking to be pampered check out the Marriott Hotel and Stellaris Casino!
All three (3) properties are less than 100 yards from each other, al with great restaurants and shops!
My recommendation is the Land Rover/Jeep tour of the island, it's a true off-road adventure and you really get to see the spectacular side of Aruba.
