Some people believe the word “vacation” is spelled S-H-O-P-P-I-N-G. If that describes you, then you will be thrilled with your options. Most hotels and resorts have shops offering a range from high-end designer clothes to toothpaste. Serious shoppers head to either Playa del Carmen or Cancun. At the former the retail action is along Fifth Avenue. At the later check out La Isla Shopping Village, Kukulcan Plaza, Luxury Avenue, Plaza Caracol and Plaza Las Americas. Still not maxed out your credit card? Then hop a ferry to Cozumel.
