Hiii... I'm from Goa its my birth place ... I'm from North Goa..condolim is a beautiful beach but it would be crowded these days due to seminars and X-mas...this is the peak session for Goa and everything will be costly there besides liquor...for one person it will coast you around 10-12k for 4 days...however if you visit some discos so much go to Tetoos and Shiva disco these are very nice and you will find educated crowd here. hope it will help you
