Hello again :-)
I have been 8 times in Patong since 2001,i have never takin any shots,other than "Black Deaths" at MTB,LOL
But be aware of any food sold from street vendors with motorbike,
i got food poisened,and lost 4 kilos in 6 hours,a terrible experience,
just thankful for my lady taking care of me :-)
Anyway as you said,better safe than sorry....
Have a fun vacation
