I had to book a last minute airport shuttle within 3 hours from the time I would need to be picked up at the airport. I was able to book and pay online before I took off. Upon arrival, it was easy to locate Discovery Mundo and they quickly called to confirm my booking and had me wait about 5 min so they could locate a driver. Once the driver arrived they were very helpful and got me to my destination with no trouble and were extremely nice and easy to communicate with.
