Valid Passport: Must not be expired and should be valid for the duration of your stay. FMM Form (Forma Migratoria Múltiple): This is a tourist permit required for all travelers entering Mexico by air or land. It’s usually provided during your flight or upon arrival at immigration. You don’t need to apply in advance, but keep a physical or digital copy with you at all times. Return Ticket & Proof of Accommodation: Not always asked, but sometimes requested by immigration officers. A copy of your return flight and hotel booking or wedding invite is a good idea to have handy.
Currency: Mexican Peso (MXN), but U.S. dollars are accepted in some tourist areas. Credit Cards: Accepted in most places, but smaller vendors sometimes prefer cash. Tipping: Common (10–15% in restaurants, small tips for taxis and hotel staff).
Cell Service: U.S. carriers like AT&T, Verizon, and T-Mobile often include Mexico roaming in their plans. Guests should check their carrier's international policies. Wi-Fi: Available at most hotels, cafes, and restaurants. Consider using WhatsApp for messaging and calling while in Mexico—it's widely used and reliable.
Tap Water: Not safe to drink for non-locals, stick to bottled water.
Time Zone: Monterrey, Mexico is on Central Standard Time (CST) and does not observe Daylight Saving Time. Since our wedding is in May, Monterrey will be one hour behind Houston. Example: If it’s 6:00 p.m. in Monterrey, it will be 7:00 p.m. in Houston. Power Outlets: Same as U.S. (Type A/B plugs, 110V). Weather in May: Warm/hot days (high 80s°F), mild nights. Pack lightweight clothing and sunscreen.
