Are special tickets needed for the Member Preview days or can we use our general admission tickets that we already received?
Suggest you look at your ticket. It will have the dates / times of its validity printed right on the ticket. As for the Member Preview, you have a choice of times to attend: either Friday, March 2 from noon to 3:30 OR Saturday March 3, 8 am - 11 am. If you come to the Saturday Members Preview, you can stay all day -- you don't have to leave at 11.
Hope this helps! If you have additional membership questions, you can call membership at 215-988-1698 or send an email to email@example.com.
Enjoy the Show and thank you for your support.
