i think the safest is going to hatyai..

if u wanna go to hatyai u can go by KTM train, drive urself or by bus or by plane..

bring RM1k and hope u will be treat like king? can dream on je la bro.. let say if want to book ayam (the good 1) almost cost u 2000 bath (=RM200).. if u are lucky enough u can bring her back to ur hotel room (that will cost u double).. & for good hotel the price is same like it in our country. thailand is not that cheap..

but if u wanna hang around experience something "different".. hatyai can be a so called destinasi bajet.. can ayat some local girl & bring her to ur lousy hotel (RM30 per day).. try siam girl.. haha.. minum there also not very cheap.

i suggest u LABUAN!! haha its heaven..

2 / 3 star hotal only RM50
3 / 4 star hotel only RM80 - 100

RM1000 is good enough to be a king there for 3 days.
but made sure you are not being slaughtered.
