I will NEVER use them again! The shuttle that took us to the airport had no AC...it's August and over 100 degrees outside! We had to wait forever to be picked up on our return trip. We saw 3 Parking Spot vans and 2 Blue Sky vans before they showed up, and they had taken so long that there were a ton of people waiting. We had a stroller with 2 small kids, so everyone kept jumping in front of us even though we'd been waiting for over 20 min (before most of them showed up). Needless to say we had to wait for the next van :( They were also slow getting people out because the lady taking payment had to also answer phones. Worst experience ever!
