As an idea, is there and option to create two zones right beside each other. One for the families and one for the 'heathens' (for lack of a better term). You could have quite a bit of fun backwards and forwards between the two in terms of chanting interplay (requires some co-ordination) but not necessarily a crazy idea (just needs some thought)
This is pretty much exactly what happens now, minus the interplay and chanting in the 'family' area. The families etc. sit in Aisle 23 next to the Fever, and your 'heathens' in 21-22.
Nearly my thoughts. If the zone got back to decent numbers, look at splitting it in two. Not next door to each other but maybe further down to 26 - 27 and try and get something going further down as well. It may help get more involved. Will need quantity though which is the first problem. Maybe for game one the numbers will be up
