Just like any other "fun card" or other passes that you pay for a day and play the rest of the year, you have to pay for parking. At $14 a pop if you go more than 3 times you are spending more money than if you got the annual pass that is actually good for a year and you can go whenever. Now obviously if you have a very large family, this could be a deal, but for one or two people I don't seeing this being much of a deal.
