What is the difference between a play pass and season pass for 6flags?

At 6 flags they offer a season pass ($100) and a play pass ($55)
Is the only difference between the two the fact that the season pass gives you a coupon book, access to the safari, and you join something online for free?
With the play pass can i still go to 6flags ANY operating day for the rest of the 2010 season?
I go to the 6flags in Jackson, NJ

What is a VPN?

VPN is (Virtual Private Network) were first used by companies to enable their employees to securely access internal systems such as email remotely (e.g. from home or while on business trips). Today they are increasingly being used for personal use by individuals to protect their privacy while online in public places (e.g. when using the wi-fi connection in a cafe) or in a country where the internet is censored / blocked (e.g. China, Saudi Arabia��).
