Vex Worlds Fast Pass

This will be our first year experiencing worlds and as coach I have volunteered to earn a fast pass. Sounds like it can be used either for skills or at the apparel store. I’m curious how these compare - are the lines usually really long for both? Is there an advantage for using a fast pass at skills? Thank you in advance. We have no idea what to expect!

Last year we had no problems waiting for skills there never seemed to be a line now the apparel store was a different story we waited at least 45 minutes
