Bulgaria Ski discussion board

Im planning on traveling to a ski resort for a couple of months this season with a friend (early jan to april). We were planning on going to andorra (we have both been there before and the nightlife is great there) However as we wont be working we were thinking of travelling to bulgaria (its supposedly cheap can anyone set us straight on this i.e how much is a pint, accomodation, season ski pass etc.).
also we are decent enough skiiers and will prob be going off piste, which resort would you recommend for advanced skiiers.
most importantly, what is the night life. we are looking for something pretty exciting, we are two 25 year old males looking for a good time.

Thanks for you help in advance
