I'm in my mid 50s and American. You can probably almost figure out from which state by my user name.
A couple of comments:
Arrived here Sunday after five weeks in Pattaya. Was surprised how hot it seemed. I walk all over Pattaya and do work up a sweat. But the first two days here I was soaked. Guess it's the humidity? Seem to do a bit better starting yesterday. Walked from near the entertainment district to Tesco and survived pretty well.
Hua Hin is almost like taking a break from Thailand when you spend most of your time in Pattaya and lower Sukhumvit in BKK. Much English is spoken and even the street vendors selling food often give you a earnest sounding thank you in English. A very pleasant place to kick back and relax. With a few fringe benefits or course.
