Hello I am coming next month to Thailand from Belgium. Last time was 2 years ago. I travel business, I am too old for economy. I will land at Suvarnabhumi. I plan to stay 50 days. My only document will be a valid Belgian passport. Can I still stay 60 days without visa. Where does I go to immigration at the airport. Does I need to register on-line somwhere, if yes please give the link. Does I need an hotel reservation. The first week visit my gf in Isaan. Can she invite me, Which document should she send to me. If I forgot something please advice. Thanks in advance for your help.
