Ichoose Kawah Putih. FO's normally open at 0930am and close at 10pm. Not sure about nite life coz I don't go out late at nite. I went to SEHAT Spa with my family. We had 2 hour massage for RM60. Superb!!

for q1. its all depend on your preference and condition. Tangkuban perahu is accessable by car up to the top where as kawah putih you'll have to wak ablit.. la..(execise loh..in the sulfuric stench.. hu hu..)
.. also tangkuban is nearer to bandung (just abt.1 hr  north of bandung)..
... kawah putih is abt. 3 hr south of bandung..

2. FO's i would think they open at standard 9.00am-9.00pm

3. Night life.. what ever you mean... are going single or couple... just to share .. they employ ladies for golf club caddies there in bandung, and those who stay there are a lot prettier than those came looking for job in this country.

4. So many spa lah there in bandung... almost on every corner.. you can try mandara, ardjuna, karang setra..(not sure i got the spelling right..)
just go and enjoy .. and you got nothing to do at night... you can just relax infront of carefoure ... kinda like dataran where the young and restless mingle..

Any recommendation for Rp350k tour guide driver in Bandung?
I'm going on the 6 - 9 april..soon..soon.. HOTel and Driver... all not book yet....
