Ask those who have arrived, how about entering Suvarnabhumi Airport at 1:00 a.m.? Take the express ?

Luggage stored at the hotel and go out to stroll. Most hotels can only check in at 2 o'clock. See if there are any empty rooms willing to give you an early check-in.
I entered from Don Mueang, not quite sure. I got my visa in advance, didn't wait, I saw people standing in line at 4am, fortunately got the visa in advance.
