You've only got a week's vacation and can't decide whether to spend it soaking up history and culture in one of Mexico's beautiful colonial cities, or soaking up the rays on the beach? You don't have to choose one or the other! One week is just long enough to enjoy a bit of both worlds. Here are a few one week itineraries combining time spent in a colonial city and time at a beach resort:

• Merida and Cancun
• Oaxaca City and Huatulco
• Morelia and Ixtapa
