Overall had a good experience with Discovery Mundo for a private airport transfer to Puerto Juarez. The international terminal was extremely busy when we arrived so had to walk over to the domestic terminal to speed up the the pickup since the driver was stuck in line to enter. There was someone there to greet us and walk us over though so was thankful for that. The driver for the return portion arrived early for the pickup so we didn't have to wait at all. Everyone we worked with was very friendly and informative.
