I got in on Oktober 23, staying for 58 days (back in the Netherlands now).
I was going to stay at my girlfriends place, and travel a bit together.
At the airport no questions were ask. Just a check of my passport (not even the boardingpass). So no inquieries about where I was going to stay (I had her address prepared on print in three languages). No proof of flight back or even when. I just got a stamp... mind you, this was my third entry this year. First in January with a visa (it was longer than 30 days). Then, after a month in Australia, I came back for 12 days (the love is strong 😊), 30 day visa exempt. And, this time 60 days exempt. Easy peasy...
This Thursday I flew back home. I checked through customs with passport (self)scan and facial recognition. No questions ask, no proof of where I had been (TM30, which we did not enter. But that could have been a problem if I had decided tot extend 30 days at immigration. It was tempting, but I didn't want any hassle and maybe have to convince an officer that I am really a tourist visiting his girlfriend, and maybe get rejected because of playing with the exempt system. And you only prolong the hurt of leaving for 30 days).
I entered Oktober 23, visa exempt, from the Netherlands. No questions asked (not even where I was going to stay, or how long). I was in line for about 30 minutes (it was busy). The digitale systems speeds up things.
Never use an agency. It's a waist of money. Entering Thailand is childsplay. Just choose the right system/visa up front.
I arrived from the Netherlands Oktober 23 (Dutch and Australian nationality). Leaving this Thursday, 58 days, so visa-exempt.
At the airport at passport check, they didn't even ask when I was planning to leave... no copy of my return ticket. Not even where I was going to stay... Just visa pages check, facial recognition and digital fingerprints.
I was here also in January/February 30 days, and in March again 12 days... (Australia in between).
