As a vendor, we purchased
As a vendor, we purchased booth space and were very disappointed! The cost of the booth was VERY expensive and the traffic was practically non-existent. Our booth was located in a bad spot (back right corner), and we only had a handful of people come by, ones that were actually LOOKING for us. I.e. they knew us already. So, VERY little benefit and VERY high cost. The sessions that I saw were well done.
The food options were also VERY disappointing. I have an allergy to gluten, and 90% of the snacks that you put out had gluten. On my first day, my "gluten-free" lunch was Vegan with hardly any protein. After that, I bought all of my own meals at other places for the rest of the event. During the breaks, most of the snacks provided were unhealthy (doughnuts, cakes, pretzels, etc)
On a positive note, I did interact with lots of very smart people and enjoyed several of the presentations.
