Moon Palace Golf and Spa Resort is a gigantic all-inclusive luxury resort along Cancun's Mayan Riviera. With 2,433 rooms across three resort sections -- each with their own decor, design, amenities, and appeal -- it's no shock that this is the largest Palace property in the world. From Sunrise's larger-than-life pool and Flowrider machine, to the charming boutique-vibe of the Moon Grand, to the fabulous kids club by Nizuc, and the standalone spa and golf center, this resort truly is all-inclusive. Just don't expect sugar-sand beaches and turquoise waters. Unfortunately, beaches in this area of town -- often smelling of and strewn with seaweed -- are far less idyllic than those in the Hotel Zone. But if you aren't bothered about the beach, this place is tough to beat.
