Hello! I have a (possibly dumb) question for you all about multiple entries into Thailand.

I understood the 5 year multiple entries into Thailand as 10 x 180 day blocks. So, each time you enter you get another 180 days but it's possible for this to run out. I.e. if I come and go 11 times, that's the visa done.

However, my friend told me that we're good to come and go for a whole five years, and leaving just gets you another 180 days to stay. So in theory you can come and go as you please within a five year period.

I'd very much like what he said to be true - can someone more clued up than me confirm please?
