Did u ever been to BKK IJ ?
Believe me 3 day is not enough !!
BKK is a paradise for guy who like play pool, shopping ( MBK ,Siam Square,Emporium..etc..), buy software at Pantip Plaza, massage at Wat Po,travel with the sky train around BKK ( full of gorgeous gal ) massage parlor in any corner,1000 girls available in the daytime ( beer garden..), great disco like CM2,Qbar,Bed and i don't talk about Go-go bar, BJ bar, no hands restaurant,clubs, coffee shop,cinema complex, etc...
And if u really need a break, Pattaya is not far.
But i still need to go to patong, every year
If u want meet other girls and others people and see something else
BKK is a good alternative.
U will like it, i'm 100% sure
