Just returned Sunday from 2 weeks in the region. 1 week in Akumal, and 1 week just outside of Play del Carmen. Rented a vehicle from Budget teh first week, and explored area to the south, south of Tulum.
Rented a vehicle the following week from Adocar, and traveled to Playa, and north to Cancun.
Both rental experiences, same as the last 21 years. Uneventful. No Policia stops, no la mordida, nothing. Nice driving, great weather, and great times.
