Concierge.com's insider take:

The seeming isolation of the location of this 1,064-room luxury tower, about two miles east of SeaWorld alongside swampland that will never be developed, lends the property an enviable natural tranquility that nearly all other Orlando mega-hotels lack. That might be enough to lure guests who crave respite from the city's usual hyperactive resorts, however even here, there's a full slate of kids' programs for weary parents. Bathrooms are enormous, with separate tub and shower, and king-size beds feel royally large, even if furnishings are a generic brand of hotel-room luxury. More enchanting still are the grounds: 500 empty acres including a Greg Norman golf course and a rambling, jungly pool area, with a lazy river that rivals the ones at the water-slide parks. The flagship restaurant, Primo, has an ever-changing menu, which emphasizes seasonal ingredients. On the downside, nearly every fragment of service carries a separate charge, including inner tubes for the pool area. Try to book one of the tower's west-facing rooms, which offer stunning sunset views. Next door, the local Ritz-Carlton outpost is a quieter, country club for high-end conventioneers. Marriott guests can use the 40,000-square-foot Ritz spa and its excellent restaurant, Norman's, as well as the pools at both hotels.
