No not really, but to be on the safe side, bring a paper copy of the page of the airline’s own website where it says that visa exempt is okay for Thailand. Or else a similar page from your local Thai Embassy stating the same.
Actually the QR website states that it is no longer required. but i had one with me too, just to be on the safe side. Dr Donna’s can be arranged in a few minutes..
Assuming you have all your paperwork done well, and carry a couple of paper copies of everything, it is all very smooth. I arrived yesterday and it was all very thorough, well organized and easy. The ATM’s directly after passport control are functioning.
