When most people think of Atlantis, they immediately envision Royal Towers -– the massive, pink, now-iconic structure that opened in 1998 and houses over 1,000 spacious rooms. It sits along a near-perfect (if it weren't for the vendors) stretch of beach in Paradise Island. Atlantis has six separate sections, and Royal Towers is the mega-resort nerve center; guests staying here will find themselves within easy walking distance of the best pools, a luxury spa and fitness center, the 141-acre Aquaventure for incredible waterslides and river rides, and activities at Dolphin Cay. Other notable features of the complex include the largest outdoor marine habitat in the world, a hopping casino, and a total of 19 bars and 21 restaurants -- all with a hefty price tag. Contemporary rooms are larger (and pricier) than rooms at the Beach and Coral Towers, but most have French balconies with standing room only.
