I was there last week and got the deal of $130 on a card for the price of $100. The go carts were $6 per person per ride and the video games were $1 each. They also offer indoor climbing courses and bumper cars, I am not sure of the price for them.
It depends on what you are looking to do there. http://www.seekonkgrandprix.com/park-info/pricing/ Use that for some pricing info from their website. I don't think it includes the arcade prices though.
