I would have to choose the Omni Orlando Resort at ChampionsGate as the best option for adults. When we stayed at the Westgate Lakes, it seemed to be a great option for families and there were a lot of kids around the water parks. While you also have families at the Omni, it has a slightly more upscale feel. You will get a sense of this with the private cabanas, tropical landscaping, and an expansive pool area with a wave pool. The Omni is a great relaxing spot for couples or groups looking to enjoy resort-style amenities. Another perk that makes it great for adults is the on-site golf and a luxury spa.
