It's unfortunate it starts so early, makes it very difficult for vendors from out-of-town to attend. Starting at 11 in London means any vendors coming from Toronto spend the entire night packing up their corals, their early morning driving, and then the next few hours setting up. The other potential vendors I spoke to from Toronto stated the same concerns, it left them totally wiped by the time the show started. If it were possible to set up the tanks the night before it might make it much easier for vendors to come in. Maybe something to consider for next year.
I personally wouldn't mind so much if I was just sitting there taking money for objects, but the last show I went to I didn't have enough energy to properly discuss my products with visitors to the booth, let alone split my effort between live food and corals.
