Swimming pools are making a big splash, as resorts invest millions to build larger, more exotic water features.
Before you take the plunge and book your next resort vacation, be sure to ask about the swimming pool. While pools as entertainment have long been standard practice at Hawaiian resorts, they have been slower to catch on elsewhere. But now that resort golf courses and spas have become ubiquitous, pools are the new way to make a splash with customers. The Fairmont Scottsdale Princess in Scottsdale, Arizona, for example, recently spent $4 million to build a new "water feature" (with a price tag like that, the term "pool" no longer seems adequate). Responding to "demand from the family market," the resort's Sue Kavanagh explains, "Travelers are getting more savvy, and while we've always had three nice pools, we needed something more creative."
The Scottsdale Princess is hardly alone in building a fabulous water facility. See for yourself with these 10 standout pools.

A cool $12 million went into the resort's "fantasy complex," which features all the favorites: waterfalls, water slides, wading pools, a children's pool, and numerous whirlpool tubs. The unique touch? A lap pool for serious swimmers. If you think you've seen this one before, you may have - it was in the Billy Crystal film Analyze This. $369-$539; (800) 999-9898;
