text: Just came back from Vegas.  And I almost missed my flight on my way home so I just need to warn other people here about Gray Line.\nOn Jan 17, I made dozens of calls to reserve my return and the line was always busy.  Because I couldn't wait in line for more than 15 minutes.   kept calling from 7pm until 10pm.  Finally I got back to my hotel room and reached someone after 45 minute phone waiting.\nOn Jan 18, the scheduled driver didn't show up on my reserved time and I was waiting at chilly hotel outside with my cell phone for 15 minutes to reach the dispatcher.  And she told me the driver would need another 10-15 minutes to come.  When I told her their driver would be half an hour late, she was very mean to say it was only 15 minute which was normal.\nEventually the driver still didn't come at next 15 minute and I was almost giving up because the time was so close to my flight time.\nBefore I went for the cab, there was another Gray Line bus dropping some customers to my hotel from airport.  The driver was initially refusing to pick me up because I was not in his schedule.  After begging with him with my almost flight, he was finally willing to pick me up to the airport with few more stops of passenger pickup.\nThere was only 15 minute left when I rushed to gate and fortunately caught my flight.
