Thousand islands (Jakarta)

Hi there,

In the week of 20 august I would really like to go to the Thousand Islands. I live in Jakarta (I arrived here two weeks ago and everything is still new to me and I really want to relax at the beach for a couple of days). I would like to get some tan.. :)
I hope someone can give me some advise about where to go, where to sleep, is a bikini accepted on those beaches, etc..

Thank you!

:)
