Without knowing the exact number (seems like last I heard was less than 1,000... don't know if that means names or seats) Ifeel like6,000 is enough. Just assuming there are 1,000 people waiting and they all want 4 tickets, that's 4,000 seats (verycrude estimate). I personally don't mind waiting because the two extra tickets I need will be for mykidswho I don't plan on regulary taking for a few more years. What's more important for me is that I'm eventually able to get all 4 together in a group.
I think a waiting list is good and right now it's still easy to find tickets if you're not a season ticket holder. I know people who regularly give away tickets, and the upper deck rarely appears to be what I would consider full. We still run specials and have family packages to sell all our tickets. I'd rather us have 60,000 fans in a stadium that seat 61,000 than have 62,000 in a stadium built to hold 70,000.
One thing I think we've got to be careful about is to still provide low cost options. I have a lot of friends who don't buy season tickets simply because of the cost. Buying tickets combined with traveling to the games can add up to alot of money for a family of 4 or 5. I guess it depends on our marketing strategy --- do we want to fill as many seats as possible, or do we want to havea slightlysmaller but probably more loyal & diehard crowd?
