I agree with the Breakers- it's the largest in Palm Beach by a lot, but in my opinion the facilties (golf course, tennis, gorgeous beachclub area with 4-5 pools, world class spa, etc), but truly luxurious and intertwined in the character and history of the island.
The Four Seasons and Ritz in Palm Beach are great too- but far out of town from Palm Beach and just less commanding in their presence. The Ritz has an absolutely fantastic Spa called Eau Spa - one of the best I've been to in the US.
I have pics from Palm Beach here with lots of facilities pics of beach, pools, spas, structure of the 3 hotels...hope it helps!
