I went there for The Yoga Conference and Show (April 9-12, 2015) and had a good time. The venue for the conference was clean and well kept. The washrooms were frequently cleaned and restocked.
It was difficult to find a water fountain or station to refill water bottles - I wish they had some in more visible areas or even near the washrooms. I found one tucked all the way at the back of the venue, and it is so key to stay hydrated as you attend the workshops at a yoga conference.
The conference itself was not bad - it was my first time attending. Lots of different workshops to attend (free in the Yoga Garden) and the entry fee was only $15 for all 4 days. There were a lot of vendors but many of the items were overpriced and could be purchased for a lot less outside of the conference. They really lacked in the food selection. You can get mainly vegetarian food, smoothies and tea. Nothing really stood out and it was overpriced as usual. You are better off finding a restaurant near by the area.
