Borovets was great a main strip of bars restaurants and a few clubs you will love it. been to Bulgaria 3 times now but my fav resort is Pamporovo its brill cant wait going beginning march.
We are going out on the 29th Dec,Not sure if you have anything planned for NewYears Eve but if you want to eat out I would recommend you book somewhere asap as it will be pretty busy.I am going with hubby and my son and daughter and her boyfriend.Can't wait,count down on.
Night life not bad , but book in advance( the night before you want to go , giving them a small deposit) for any restaurants, as are all quite small. and don't take large parties....
