Reply to Best place to go on a party holiday ? (Ibiza, lloret de mar, ... ?)

So myself and three other friends want to go on a trip to someplace near the mediterranean this summer.
The main goal is to go party every evening .

What country/town would be ideal for this ? We 'd prefer to go to an upcoming lesser known town instead of an established one.

Please share your own experiences.
How were the girls, how was the beer, the music, etc.
