Check out the four top ways waterpark resorts are attracting adult guests:

1 Day spas. Body massages, manicures, pedicures, facials, body wraps, hair treatment, the works. Waterparks are becoming synonymous with deep relaxation.

2 Fitness and yoga. Exercise your mind and body, be one with the energy of water. Golf, tennis and horseback riding. Recess for the grown-ups.

3 Fine dining. Nothing says ?adult? like fine gourmet meals. Linen tablecloths, candles and black-tie service are just a few ways to make your dining area decidedly grown-up. Consider hiring a noted chef to really wow adults and their palates.

4 Theming. More Fantasy Island than fantasia, adult-oriented theming uses upscale materials and incorporates more natural elements into the design. No bright-colored plastics allowed here.
