Interestingly, the hotel has rates as low as $299 over the Christmas holidays.
I just booked a Partial Ocean-View, inclusive of FHR amenities, for $349 a night. Extremely, extremely reasonable. The one strange thing, the 50-day cancellation policy. I appreciate that its a busy time and that they'll almost definitely sell out. However, why are they selling rooms at what are only mildly above summer rates?
Either way, it works out, as I need to be in Palm Beach just before Christmas and the Four Seasons is all of 500 yards from the friends I'm visiting.
Something to read carefully if you intend to book over the holidays, though.
