Ok, I honestly don't remember much, but I knew I had an amazing time based on my pictures!  It was extremely packed, but the venue is HUGE!  There are 5 floors for goodness sake... all with a different theme and all with different types of music.  There are a lot of little spaces and rooms all over the place to sit and take a breather from all the craziness.  I'd definitely recommend it and would go back if I'm ever in Edinburgh!
