I buy the 6 day. You cannot get a six day without the plus. We are not that much into water parks. I wish they had a six day without the waterparks that was cheaper.
We like buying our AP's & then getting 2 trips out of them. We bought AP's for our Dec 2002 trip & then used them again for March 2003. We let them expire & will buy them again for our late Sept 2004 trip & then will return for a week around Labor Day Sept 2005. (We're also hoping for a quick weekend trip to visit family in Feb 2005 on our AP's too!)
