You'll feel as if you've slipped into another world at The Spa at The Omni Grove Park Inn. This haven is sprawled across 43,000 square feet and features beautiful rock walls, arches and tunnels. Water is a major aspect of the spa with several mineral-based pools, two waterfall pools, a lap pool with fiber-optic stars and soothing underwater music, and separate pools for men and women. In addition, there are more relaxation spaces at any of the three fireside lounges with over-sized chairs. A nice range of massages, facials and body treatments can be found on the menu. The spa books fast, so it's recommended you schedule treatments when you reserve your stay.
