I showed up at the airport after a 26 hour flight from Canada to find no one there. I booked a private car from Bangkok to Pattaya. I found the tourist booth and they phoned the man in charge. He showed up and told me I was not on his list. I showed my printed out and he then started to make calls. I arrived at 2:00 in the morning and about over an hour later a car arrived. Driver was good and polite. No one apologized to me or said they were sorry.
As always a Rep' is waiting for you at the arrivals gate, they have never let me down. You are lead away to your transport with the minimum of fuss and the car or bus is always clean with good aircon'. The drivers do not always know every hotel so it can be quite interesting when they get on the mobile phone to be 'talked in' to your destination!
