playing tour guide in Bangkok.HELP!

[mermaidnz]

so a really lovely customer of mine has paid for me and my friend to go to thailand with him for 5-6days next week, she has never left the country and is happy to do almost anything, and He has never been to Bangkok,which is where we will be for the whole time.

ive been nominated as tour bitch, since i have been there so many times,which is awesome, i love researching and booking stuff, BUT, i havent been there for a few years,and things change, can anyone tell me any really cool new things that we HAVE to do?

ive got a day at temples and museums etc
a day at Kanchanaburi-if someones game enough to drive,ill navigate to tiger temple and river kwai elephant rides.
a day shopping-chuctchuck and MBK and siam
a day maybe safari world and general city exploring??

but what else?

we are keen to go to the ping pong shows for sure,and maybe spend a few nights our drinking or eating out- i have NO IDEA where o go for this either, i have never gone out in bangkok at night...any suggestions on good resturates or bars....maybe not too young of an atmosphere tho.

much appreciated!!!
