Here's a few thoughts from a relative noob to the scene...
I thought the venue was perfect for the event. The CRTs, comfy chairs, projection screen to watch streamed games and the streaming setup were all top notch. For people looking for stuff to do, I would suggest staying in downtown Toronto and "Ubering" to the venue. That worked out perfect for Big E and I. It was approx a 30 minute ride and cost approx 35$ Canadian each way(which is basically free ).
Food and Alcohol
The lack of food options and alcohol kind of sucked although I think this could be an easy fix. I thought I heard some talk that Ewaves is looking into a liquor license. Not sure if that will happen. As far as food, I'd be willing to pay more for the event if the event were catered. Just a thought. Food trucks are kind of a big thing in the states right now, not so sure about Canada. But a local food truck could be a catering option too.
Choice of weekend
My only other mini-suggestion would be to try and plan the event for a weekend when there is a little more going on in Toronto. We looked into Bluejays (they were away) and Mapleleafs (preseason) but ultimately ended up an Argo's game. Argos were awesome but It would be cool to catch one of the major professional sports teams if the event continues in Toronto.
I had a blast. Best weekend I've had in a while for sure. Halifax and Smoz did an unbelievable job setting up this event. Awesome to see all of you guys, KingRaph, AJ, Tex, EA, Aqua and the rest of you. I've only met Coach once but I was definitely looking forward to seeing him. I hope to see Coach and the rest of you at the next event.
