Mix it up for the first few weeks, keep part of your show and then just do a standstill. That will satisfy your administrators and your crowd.

Shorten the amount of time that you need for halftime by just performing the First movement of your show-(then cadence to the beginning of the last movement)-Last movement.

Or…

March one movement (the most exciting part of your show that the crowd will enjoy) then move to a block Band to play a pep tune or two to feature either the drill team, or the colorguard, or the cheerleaders in the standstill pep tune.
