Thanks for the tips, Mr. South and Mr. King
I will review them and ask some questions.
For now, question to adultking (since South says Yes to that) - am I careless deciding not to take any vaccination?
I have strong immunity (never been sick in my life with anything, even with high temperature/cold, well maybe 1 day every 2 years I get a quick cold) and do not want to mess with my immunity taking those vaccines.
I read that most people do not take vaccines just for a touristy trip as well.
What is your take?
Ps: interesting thing about "hot season", at least for BK:
https://en.wikipedia.org/wiki/Bangkok#Climate
It does not look that any month is much hotter than any other one
Coldest month of the year is only like 10% colder than the hottest one.
pps: precipitation numbers in that table also looks close to the rainy months, that is why I assumed May is semi rainy season
