IMO one reason to attend is you are presented with four Seminar times each day and in each time slot you have a selection of 4 to 6 (estimate) topics.
Some Seminars are just "Info-Mercials" others like "Ask the Experts" are all "Info" and no "mercial". Some technical seminars are offered by various chassis MFG and others by component MFG like refrigerator or furnace co.
has a list of seminar topics on their site
I happen to be giving two different Seminars on Tires and Three different seminars on Genealogy over the four day period March 17 -20. I am selling no products or subscriptions and am not sponsored by any company so I consider my seminars 100% Information.
If you have questions on tires or just want to talk Genealogy stop in and we can talk.
