I am a girl of 34 years old and live in the north of Spain.
I planned to do a tour of Southeast Asia and a half months. Myanmar, Thailand, Laos (Luang Prabang), Vietnam, Cambodia (Angkor), Singapore, Malaysia (Kuala Lumpur).
Maybe it does not fit with your idea because you just want to be in Thailand, but just in case you leave the comment.
My idea was to leave by the end of May and early July return.
