Thanks for all the replies! So the last few times I flew into Thailand (Jan and most recently April) I didn’t bring any cash or printouts of my hotel and flight itineraries. I think this time to be safe I’ll bring my hotel and flight itineraries, but I still rather not have to keep the 20k thb or equivalent in cash on me. Have any of you had Thai immigration officers ask to see that you have enough cash on hand? If needs be I can keep the cash on hand, but like I said, I rather not.
