Those are great!
I'm going just south of Cancun in January did you have any trouble in and out of the airport in Cancun or while you flew any down there?
I would download the dji go app and see if it has your area as a no fly zone. All the airports in my are are a 5 mile no fly zone but the app only has right around the airport so if u are 1 mile away the p3p will still fly.
