Depends on how much you stop and talk with the manufacturers. Look at the map, and make you sure to hit the places you want to see on day one, then stroll through the rest of the days. That is what I do. HEMI Joel on the other hand talks to every vendor possible, and I'm not sure he has seen everything, going every day for the last 2 years. Oh, and if you are walking in a group of people, forget seeing everything. Split up, and have a meeting time. Works much better that way.
