Which airport are you arriving at: Suvarnabhumi or Don Mueang International? I would not advise you to order a taxi or look for a transfer on the spot, because they usually have a very high surcharge and can even cheat you as a tourist. I ordered transfer Thailand on the GetTransfer website in advance and even when our flight was delayed for an hour, the driver was still waiting for us to take us to the hotel. You will not need to stand at the airport with suitcases, and you will immediately get on the transfer and comfortably reach the hotel. How many people are you planning to go on this trip? You can immediately order a minibus if necessary, when you choose the class of the car.
