Jesse, we were there early last year (my first time in many years) and there was plenty of parking there. When we went out to the car with our many purchases there was always some parking spots available. There is a very good snack bar in the building as I recall. I don't remember about entry costs but I believe it's one entry cost for the NNL and not per model. But keep in mind there is a entry fee for the toy show and a separate one for the NNL. You can start entering your models as soon as the NNL opens. I don't believe there is a cut off time as it not a judged show. Hope this helps.
Bill, Think of one big auditorium. Then in a corner of said space there is a boxed in area of tables with only one way in or out. Obviously you can see some of the models from outside of the designated area but if you want a closer look and a chance to talk to all the model builders present, you have to pay to get into the NNL Area. I was a little surprised last year but got used to it pretty quick. There were three of us there last year. We're known as shoppers as much as builders. But I said I came here for the show and the shopping was secondary (although I did my fair share before the NNL started). The other 2 sat outside the area and waited after they were done shopping and would not pay to view the actual NNL. I was thrilled to meet Tim Boyd and have a chance to talk to other car model builders that I've met throughout the years. I look forward to seeing you there as well as Dave Van and anybody else that I know or from this board etc.
