Paperwork

Make copies of your passport, airline tickets, and hotel and rental car reservations. Leave one copy with a family member or friend at home, pack another in your suitcase and a third in your carry-on bag. In addition, register your trip at the U.S. State Department web site just in case there is a emergency situation in Mexico or family members need to locate you. Also, make a note of your credit card numbers and customer service telephone numbers, and pack two copies in separate places.

Communication

Chances are your cell phone will work in Mexico, but check with your carrier before you leave to see how much it will cost. Opt for for an international plan that will save you money and be sure to check the likely costs of data transfers and instant messaging. Take along a small phrase book, also. Many Mexicans speak English, but telephone information operators and residents of smaller towns may only speak Spanish. Plus, it is always a sign of good manners to attempt to say a few words in the local lingo.

First Aid

Mexican pharmacies are well-stocked, many hotels and resorts have a doctor on call, and city emergency rooms are well-prepared, but an accident can happen at any time, atop a pyramid or on a quiet beach, so pack a small first aid kit. Be sure to include over-the-counter pain and stomach discomfort relief, alcohol swabs, and adhesive bandages designed for blisters. Hand sanitizer and small packets of tissue also are handy, since some Mexican bathrooms can be less than perfect.

Extras

There is a good chance you will bring souvenirs home from Mexico, so take along an extra collapsible bag for your haul. Textiles are easy to pack, but those ceramic treasures can be a challenge. Consider stuffing sections of bubble wrap in your shoes inside your suitcase if you think you likely will succumb to the charms of Mexican pottery. Pack a few plastic zipped bags, handy for packing wet swimsuits after that last-minute swim before you fly home.

• During the winter you may need a light sweater or sweatshirt for the occasional cool evening.
• At least 2 swimsuits
