This is the second year we have used Discovery Mundo for our airport to hotel transportation in Cancun. I was a little nervous doing this online with a company I didn't know. Both times, they were there waiting for us coming and going. This time from the airport, we had to walk to the other side of the airport, but it is so congested there it was not the driver's fault. We were picked up at the Riu Caribe for our flight back by Alberto. He was so friendly and personable, spoke perfect English and gave us tips for next year and we, of course, gave him a tip. Will use them again.
