I do not recommend Keddy in Cancun due to a terrible experience I had in January of 2022. They refused to accept my insurance and attempted to insist I buy insurance from them at a highly inflated rate. I ended up losing my pre-payment for my rental vehicle. Overall it was a frustrating and seemingly predatory experience. If you rent from this organization, either pre-pay for insurance or ensure you have a letter that details your Credit Card Auto Rental Collision Damage Waiver benefit and documentation on how it complies with the Mexican CNSF (Comisión Nacional de Seguros y Fianzas) regulations. Even with all of that, I suspect Keddy will invent some other "required" documentation that you don't have to force you to buy their inflated insurance coverage. Beware.
