I'm holding out to see if Groupon will be doing an offer lol
We went to Erotica 2010... the exhibition itself we thought was pretty poor to be honest... I have been going for a good few years and each yr the event itself seems smaller, and more dissapointing to be honest.
However we did attend the evening ball, and thoroughly enjoyed that! Be warned you do have to make an affort or you will NOT be allowed in. We did see a few people who had valid tickets turned away due to the fact they simply didnt make the effort in dressing up.
It's not for everyone, but we really liked it (and are regular TG goers too, so this really was right up our street)... not cheap once you include hotel, costumes etc....... but hey like Xmas.. save for it ;o)
Give it a go, make the effort and have fun!
