thank you for the great info.... I am also looking at the same option multiple entry coming from Germany
My question would be do I need a return ticket when flying into Thailand? I plan to come in November and returning back to Germany end of April.
Also planning 1 or 2 weeks Vietnam and a few days Singapore.
I am not sure if I should book a one way in November to Thailand and a flight out to Vietnam after 90 days since it is possible to extend the 60 days to 30 more on each entry.
