China’s neighbors -- Thailand, Malaysia, or the Philippines -- tend to corner the market on warm, tropical Asian getaways. But located only 14 miles off mainland China and roughly the size of Belgium, Hainan can compete on its own, thank you very much, abounding with amazing seafood, fresh coconuts, luxury resorts, and fun watersports.

Pros: Great value on points, free breakfast each day, stunning location and design. Cons: Leaky shower, and it’s only open for the summer.
