If you have only 2-hour card, you won't ride much because of the long line all the time. It's kind of slow when they let people enters and out. It really takes a lot of time for only that. Besides, when the people from the b-day party come in, you will stay in the line more time. You already waited for long in the line and more when b-day party people come in because they prioritize them. And, when you get in, not enough rounds you can make to drive. Mostly, stop then drive, stop then drive. no excitement that way. Oh my!
