Yes resort fees are one of those things that really tick me off now. Certain areas it is becoming a joke... try to go to Vegas and you can find a room for 39/nt but then there is a 25 resort fee.
Its yet another junk fee that hotels are using, just like airlines. Except in this case, you really aren't getting anything for the fee. Use of the beach and chairs and a couple bottles of water. Seriously, if you're staying at a beach property, the beach should be included in the room, not tacked on as another crap fee.
Oh and make sure you get your two bottles of water per day at Frenchman's Reef. I had to keep going after them for it since they 'forgot' to put them in the room when it was serviced.
