2-person and 4-person box seat experience with select your own seating

Hi all --

Last season we turned off the select your own seat functionality so that we were able to socially distance guests. Since we were manually seating guests anyway, we created 2-person and 4-person VIP box packages that were sold online to "buy out" our box seats. In a typical season where patrons are able to select their own seats, we would not be able to funnel individuals into buying as a group of 2 or 4. It would be possible for a single individual to buy one of the four seats in a box and have 3 unrelated individuals purchase the remaining seats. We'd love to be able to continue to offer the VIP packages for this season, but I don't know if there is a way to force patrons to purchase the experience in groups of 2 or 4. 

Any guidance or thoughts about this would be much appreciated!
