Best Indoor Water Parks

There are dozens of indoor water park hotels. But not all parks are created equal. And the biggest ones aren't necessarily the best. Conversely, relatively small indoor water parks can pack a lot of watery fun into a tight space. Which ones make the biggest splash? Before you go shopping for a new pair of Speedos, check out About.com's top-10 picks for North America's best indoor water parks.

Number 10: Castaway Bay

• Location: Sandusky, Ohio (located next to -- and operated by -- Cedar Point)
• Indoor Water Park Square Footage: 38,000

Cedar Point, home to the world's largest (and some might say greatest) collection of roller coasters and amusement rides, also offers year-round fun with Castaway Bay. The compact indoor water park features plenty of activities, including the Rendezvous Run indoor water coaster, a wave pool, the Lookout Lagoon Family Funhouse (with the ubiquitous water park tipping bucket), and The Grotto, an indoor/outdoor whirlpool that offers plenty of hot tub yin to a cold winter day's yang.
