I'd normally be going on the saturday. I went last year and really enjoyed it. Had a great system too - Boyfriend came and installed himself in the pub just next to FOQ (inside the NEC) for the day. I had someone to eat lunch with and to leave lots of shopping with, and he watched the Olympics, and didnt see how much I spent! I certainly didnt have a problem with vendors not having enough stock either!
This year I promised myself I wouldnt go since we're going to America on holiday in September anyway. Plan to take a spare bag there instead.
