Cancun
In the Mexican Caribbean, Cancun is one of Mexico's most popular destinations. The winter months are the peak seasons, and the summer and fall, during hurricane season, the low months. Hurricanes are a real threat in the area and you should plan accordingly.
There are many options for adventurers, vacationers, or foodies alike in Cancun. Swim the the dolphins, snorkel, go scuba diving, or simply lounge on the beach. Head to La Isla if you want to do some shopping. The Moon Spa and Golf Club is the best place to play golf in the area. Cruise ships keep Cancun popular, so you won't find the beaches isolated, but it can still be a relaxing vacation. Nightlife is always active in Cancun. If you want to escape the tourist crowds and see where the locals hang out, head over to Yaxchilan Avenue for an evening of club hopping.
