The brother at Plaza Indonesia if you are worry of going to local place and want some girl, you can try BATS, it's at basement of Shangari La, many girls there waiting to pick up home, general price is 100 USD to 150 USD, they stay overnight at your hotel, if you are good at muliple over night it's good value also....
if borther go Jakarta for fun and worry can PM me, I may help you sort out, if I am there I will hang out with you all, I am early 30 man, good experience in South-East Asia party...
Stay by yourself good price will be Novotel Manga Dua, a bit far from Central Jakarta, good price 5 stars will be Hotel Sultan, a good place to book ticket will be www.agoda.com they have many hotels at Indonesia, don't book Park Lane (5 stars) as it's old and facing 墳場
