I contacted them for a 4 AM pickup to the airport. They said it would be no problem as they can schedule 24 hour of any day. So we booked it. When the day came, we waited and waited. At 4:20 we called and got the voice mail only. We left a message and drove to the airport ourselves. We never did receive a call back from them. I have avoided their service since then and life has been much smoother. I suggest you do the same.
