Cancun. Need I say more? The beach bars are like Venus flytraps filled with Jell-O shots, or something, but you really can have some non-Spring Break fun here if you try. There are the archeological sites at Chichen Itza and Tulum, the magnificent island of Isla Mujeres, and, of course, the beach at Cancun itself. One of the more highly-regarded resorts is the Royal—if you’re into sprawling, soul-sucking concrete palaces with 288 satellite-TV-equipped rooms, eight restaurants (with cuisine covering four continents), 14 bars, a jewelry store, and unisex beauty salon. Ugh. But hey, if that’s your thing, by all means. Rates start at $647 a night.
