I'm planning a family trip to Mexico in the summer. I'm a US citizen and so are my two kids. My wife was born in Mexico, but recently became a US citizen as well.
Traveling to Cancun, Mexico our flight will be making a stop in Guadalajara, Mexico continuing it's way to Cancun on a different plane (flight). We will be in Cancun for nine days.
Should I be aware of something? Mexican visas, or anything else?
