I have 4 this year, direct from Munich to Bangkok and not longer than 60days. Last entry was last week on 11th... No issues or word from immigration at BKK.
Will have another one mid of December.
I think the problems only accur when using land border(s) and having more than 2 obviously stretching the 60days + 30extension limits.
thanks for advice, I was also wondering why immigration at BKK didn't mention something but that might be due I was leaving the country long time before visa exempts ever expired
exactly same I do in case of insurance... I can put my mandatory German public health insurance on hold for 70€/month when longer absence from EU (as I am 'covered' in EU) than 3months continuously so I can spend that big amount of money (500€/month) on my own decisions and insurance coverage for SEA.
