I am staying by the airport is there any shuttle service from the airport to the convention center?
Well, one available is -
There's that company, and also I believe a bus line from the airport, but there are no official Gen Con shuttles this year.

If we drive ourselves to the event daily where can we park? Cost? If I can go ahead and pay for parking where on the website do I find that information? Thank You
You can search in Events for parking through Gate Ten, or look at a website like Park Whiz. There are also several other threads in the Travel area of the forums where people are discussing parking.
