The Pointe at South Mountain wasn't too shabby, but $52 mil can buy some killer upgrades and an awful lot of water. That's why the remodeled luxury hotel, now called the Arizona Grand Resort, was a shoe-in for the best pool in town. Actually, calling the Arizona Grand's Oasis Water Park a pool is a bit like calling the Desert Botanical Garden a nice yard. There's an eight-story tower with three water slides, a huge wave pool with waterfalls, and a faux river perfect for inner tubing. Order a frozen margarita at the swim-up bar or relax in the 25-person hot tub while the little ones play beach volleyball in the kid-friendly Wild Cat Springs. The only downside is that Oasis Park is for resort guests only, so you'll have to sneak in, splurge for a romantic local getaway, or schmooze your way into a company freebie.
