The hours of the exhibit hall was a definite problem. I arrived on Saturday morning and my first class did not start until 945, only to find exhibit hall did not open till 9:30 AM. So I had 15 minutes and I spent it with one vendor.
While there were adequate hours to sneak in between classes, due to the poor facilities of not having power outlets or tables, I found myself constantly trying to find outlets to keep my electronic devices charged so I can take the kind of notes I'm I'm used to taking. Thus the exhibit hall time suffered. In order to make sure I had a seat after the debacle of the anterior segment class, I arrived to the two other classes in that lecture hall, half an hour early just to be sure I would get a seat. In every class in that room, someone did not have a seat.
The vision expo application however did provide good information including contact information for any of the companies that I missed, so I can contact them as well as visit their website to learn about the products.
As far as talking to other OD's, some of the best doctors in our profession were present, and it was a great opportunity to network if you wanted to.
