Jim,
It does not matter if you are charged or not to get in. Even if a person gets in free they should be able to have faith in the fact that they can look around all they want & take their time up until the 4:00 P.M. closing time. As for "Advertise the show 10 till ? on Saturday." that makes no sense at all! It leaves everyone guessing how long they have to enjoy the show. Don't forget, not everyone is able to be there all 3 days. You do have quite a few people who can only come out for the weekend & their only day at the Convention might be Saturday............Andy - Las Vegas
