Go to YouTube .. type in Hua Hin maybe Hua Hin beaches ...
I've been to Jomtien , Pattaya, Rayong , Bang Saen , Sericha ... all have tons of crap ... most Hua Hin beaches looks like they are swept daily with white fine sandy beach ..
One thing I know about Thailand ... Thailand has everything u want , you just need to look at the right places, imported items may cost a bit more but it's all here ... it might even be cheaper since u don't pay that much taxes on most items here .:. Buy it when u need it , don't need to bring anything
Forgot to add , I also have a Thai passport, but I just got my new USA passport and wanted to fill my pages with many immigration stamped like I did my older passport... paid the price for playing stupid games ..
I made that mistake in 2021... I had to pay penalty for overstay and also visa extension..: dumb move ... use the thai passport to come into Thailand and go out (plus thr lines are shorter) then use the USA passport to come back in to USA and also leave USA
Go to any foreign country without a plan where a tourist visa is 30 days and plan on staying for 6 months ... when u get caught you will pay a hefty fine and will get blacklisted and won't be able to come back for many years ...
