a few suggestions..
the only way we have gotten away with pfc is to offer coaching.. you have to convince the ski area that this coaching is helping to make their terrain parks safer in the long run. plan on doing a orientation with terrain park ettiquette and procedures this goes a long way
volunteers.. get everyone to volunteer.. cat drivers.. food prep.. coaches.. diggers.. lift attendants..
trade these volunteers for hours on the hill.. tom, tad, stephen, and I all volunteer our time for the weeks it takes to setup pfc.. it goes a LONG way to make sure the ski area knows its personnel costs will be low. (cat drivers are the most expensive.. so be sure they want to do it for free..)
trade/get sponsors.. get your ski areas food providers on board to donate food.. try to get the fuel providers to give you some fuel for the cats.. we burn a ton of money in build costs.. talk to anyone you can about donating money or goods to give away.. and if anyone does give you anything.. thank them.. A LOT.. send letters, talk about them at camp etc..
coaches... to get enough people to come.. you need to have stuff for the advanced riders.. which all your coaches want to hit.. you almost need a coach supervisor (stephen in our case) just chasing coaches and making sure they are teaching.. the younger kids that need coaching are usually terrified of asking for help.. you also have to find them and put them with a coach.
features.. have at least 4 boxes/rails that are ultra beginner.. they will get the most use by far.. and at least one ultra small jump.. everyone loves them.. and you can learn damn near anything on them..
we have to convince perfect north to keep paying premiums for the normal season until pfc is over.. and i think we end up getting special event insurance as well.. that by itself is pretty expensive..
i am sure i will have some more suggestions after next weekend when pfc7 is here and i am doing all these things...
