The 311 rooms of the Casa Marina Resort have a light, sophisticated, but still island-y feel, with neutral tones, sheer curtains, and sleek hardwood or tiled floors. The resort also offers great in-room amenities, including free Wi-Fi, flat-screen TVs, and espresso machines. Although bathrooms aren't anything grand (just simple walk-in showers or shower/tub combos), they're clean and sleek. The resort's grounds are beautiful, with palm trees and lush foliage, and lead to a rare amenity in Key West -- a swimmable beach. Although it's too rocky to wade into the water, a long dock extends to sandier bottoms.
