I would suggest to the powers that be at Gencon that you consider expanding the VIG program rather than adding additional limitations such as limiting companion badges, etc..... Based on the lottery this year the demand is there.
This is free revenue for Gencon. Yes, there is some limited admin costs but add 500 or even 1000 more VIG's and slap a $600 or $700 price tag on them. There is at least another $300,00 in revenue and possibly alot more.
I see no reason to not do this? Some will decry the cost and claim it's not fair but it's nothing more than the free-market and life isn't fair.
Another good option to generate more revenue would be to sell the VIG options a la carte. Limit the number of available participants of you want. For example (just numbers I am making up)...
Early Hotel Registration - $200
1 hour early into the Dealer room - $100
Use of the Hospitality room - $100
The people who would never consider the VIG program would never pay this but many of us would. I will stress again, this is free revenue for Gencon that could be put to good use.
