I haven't heard of this. Do you have a link?
I'm guessing this refers to the VIP experience for 199$
Pit = general admission (not a designated seat, but GA pit will be in the front right up by the stage. If you can stand just fine for several hours, I'd say this is a good thing! :)
Will call means that you will pick up your tickets the day of the show at the venue. There will be a "Will call" window or table in the venue, typically near the ticket/box office. Bring your ID and the credit card you used for the transaction to verify your identity. You may only need your ID, but always a good idea to have the payment source as well.
Have fun at the show and come back to give us a review about it!
GA pit will be in the front, standing room only - meaning first come, first choice where to stand. Reserved seating are still good seats but you have a designated seat (as linc26 said) to sit in rather than first come, first serve.
Try to look at a layout of the venue for more details on either the specific venue's website or ticketing agent's site if available.
I think the pit means u just stand kind of anywhere so specific seat and or section and reserved seating means u have an assigned seat and section
AMEN TO THAT!
