Are we talking club parties, bar parties or private parties??? The party calender in the nightlife section of this site has all the club listings, Kanya host Garlands parties which are always quite mad. Tuesdays they are.
If I had to pick partys to go to in the time you are there, I'd say any Sundays@Space or Pacha 30th Renaicance on 5th September - Tong and Sasha. That one will be hot!
