Well done for putting on a great event - can't comment on the cabaret as I didn't attend but the day itself went very well and I thought the organisers coped admirably with the constraints of the venue.
From a personal viewpoint, having been off 'the scene' for several years I found it very heartening to see so many people there and to get back in touch with people I hadn't seen for years as well as meeting new folks.
(And the kink panel alone was worth the entry price!)
