I agree with you on the size becoming an issue. It was so large, and spread through so many rooms, that it was actually difficult to find the vendors you were looking for. The map was useless, and completely incorrect in some cases.

I happen to do trade shows in other industries, and you can't completely get away from the bag toting people that only want free stuff. It's a side effect of any venue like that.

Also, it seems as though people these days lack the courtesy and respect to not waste a salesperson's time at a show unless they have a genuine interest in purchasing a product.
