I've stayed here three or four times, including a four night stay two weeks ago. It is the single most beautiful resort I've ever visited.
Each time I've been upgraded to Emerald Bay, the resort's deluxe rooms. The rooms have walk-in marble and glass showers, dual sinks, robes and heavy, oversized furniture. The soaps are all oatmeal, which I love!!
The enclosed atriums have three or four distinct parts -- the Everglades (with an appropriate bayou setting), Key West (it has a HUGE ship that is actually Sunset Sam's seafood restaurant), St. Augustine and Emerald Bay (both overlook a huge Spanish-style castle, and some overlook the lush greenery surrounding the gator area). Where you want to stay depends on your lifestyle -- I LOVE the Everglades, but can never get a balcony there. It's super quiet, too. Key West is fun and if you get a balcony there, you can sit on it with a drink and listen to the live music. It can be loud, however.
The restaurants are, indeed, expensive and cater to business travelers on expensed budgets. We always make a run to the Publix in Little Lake Bryan (behind the Premium Outlet mall).
There are two pools -- the kid's pool which has a cement octopus that shoots water out of its tenticles and seahorses that spout water into the pool (it's ADORABLE) and a quieter, adult pool. We always go to the Marine Pool just because it's so much more fun!
Let me know if you have any questions. We're staying on-property in October, but I'm afraid the Gaylord Palms has spoiled me forever...
