I literally cannot fault this hotel. It's absolutely stunning, everything about it from the rooms, to the staff, to the food, are fantastic. I cannot think of a more beautiful hotel anywhere in the world. That said, the area didn't really do it for me. As a Scottish family stopping at the beach for a few days after a week at Disney, i'd advise those in similar circumstances to possibly try the key's, Naples, longboat key etc etc for a truer Florida beach vacation. Palm Beach is more a very exclusive residential beach town than a laid back, chilled beachy sort of place.
All in all, i'd return because of the hotel, and all that it offers, especially for families and those seeking a top end hotel. Expensive? It's all relative to what you can afford. I think it represents value for money and you can clearly see why the it costs what it does to eat and stay here. If you're visiting the area, it's a fantastic hotel.
