Hi, I was wondering if FP are really necessary for BatB and for the Frozen Sing a long? We've been able to get in to BatB before without FP. Any comments? Also what is the seating like for the Frozen Sing a Long? Floor, bench? How big is venue? Thanks much! We will be at HS May 1st. We can reserve FP on Feb 25th. Since they are such a hot commodity I don't want to waste any we don't need! Thanks again!
