This year only the person with the pass, and one.. I did say one, other person can join along.. Still, you will want to contact guest relations, as they will tell you about the policy.. If the wait is more than 30 minutes, you'll have to get the attractions boarding passed (that you got from guest relations) signed by the ride opperator (either at the greeter booth, or in the station).. Still kinda confused on this part, but I *think* there is also a line pass that you can have your party wait in line, and then you get your boarding pass signed, and then the times should work out to where you can ride together.. I'm unsure about that part, but I do know that the Boarding pass is for the person who it was issued to, plus ONE other.
Like I also said, be sure to call guest relations before your trip.. They can explain it and help you out more than anyone.
Hope you have a great time at the park this year! Can't wait to ride some rides again!
