After its $25 million makeover, this 650-room Marriott in Fort Lauderdale is great for kids -- giant pool, kids' club, big, comfortable guest rooms -- but there's still plenty for grown-ups, including yoga classes at the fitness center, an adult-only pool, and a full-service spa and salon. Just watch out for the nickel-and-diming.

Right across from the beach, the Westin's strong suit is its wealth of amenities: a kids club, a Starbucks, an outdoor event space, and a well-known steakhouse, for starters. The hotel re-opened in early 2010 after a major renovation that left it with a clean, modern design full of beachy accents.

The first in a new brand of "B" hotels, the all-white B Ocean sits just across the street from the beach, with an austere, minimalist design -- similar to the style of a W hotel, with subtle neon lighting in the lobby come nightfall. The ocean views are the star here, but you'll also find two great restaurants and a small pool with an accompanying outdoor bar. Despite a trendy appearance, this 240-room hotel is popular with families, and it's not uncommon to see kids splashing in the pool or eating dinner in the restaurants.
