@steve, @lucky:
W Fort Lauderdale is tolerable and they do a good job of upgrading Platinums. I'm not big on the poolside party scene, but many guests forget that there's a second pool that is peaceful and offers free cabanas on the west side of the hotel with intercoastal waterway views. I've consistently received upgrades, most recently to a "Sensational Ocean Front Suite" with huge balcony but most often I've requested upgrades to their residences with full kitchen and laundry which were granted.
Next year the Conrad Fort Lauderdale will be open and that should be a good option. It's being converted from the failed Trump condo hotel project which was built during the financial crisis and never opened. That also means that a one-mile strip of Fort Lauderdale's beach front will be great for mattress runs for SPG (W, Westin, Sheraton locations) or Hilton (Conrad, Hilton, Doubletree locations).
If you stay at the W, Steak 954 offers a decent brunch and is bookable for points on Open Table. Next door in the Hilton is great new restaurant called "Surf, Sun, Sand" which is good for lunch or dinner and also on Open Table. There's also a Truluck's in the Galleria Mall which is a 5 min drive from the W and has a happy hour with half-price cocktails and apps plus a piano singer.
