A replacement arena here will not have the number of luxury boxes that Staples has. No Sacramento could not support that. It would likely be closer to the number of boxes San Antonio has, another small market. I don't have time right now to try and find it, but there was a great article about the success of SA and about their arena and the relationship with the fans and city. One of the things the owners said was that the money they get from the luxury boxes allows them to keep tickets prices down for seats for the average fan. In other words, part of the reason average joe pays more for seats at Arco, is becasue he has to make up for the lack of revenue that can come from luxury boxes.
Arco was cheap to begin with (it was paid for with private money) and it has not worn well. So do you spend millions of dollars to maintain it (I believe I read that it needs a new roof) or is that money wasted on a facility that isn't really very good to begin with? It is inadequate for many major events. The Bee reported not long ago that many acts/shows aren't booking in Sacramento, becasue there is no facility (Arco) adequate to meet their needs physically and financially.
The only other arena I've been to recently is the United Center in Chicago. The seats are roomier and more comfortable, the concourses are very wide, so you don't feel like you might get trampled to death at any moment (I have almost been knocked to the ground at Arco by the tightly packed mob). There are stores and a greater variety of eating choices. We sat about 10-15 rows up at one end of the court. The seats were $100 each. It was not as intimate as Arco, but the Maloofs have insisted they don't want any arena that won't maintian the atmosphere of Arco. They don't want it to seat more than about 18,000 either. That's also to maintain intimacy. Of course, less seats helps keep demand up, too.
Oh, as to price, I can't go to many games, but I've gone to games for $10 to $25 a seat. I usually avoid the food, which is very costly (at any arena or stadium). There are loads of tickets in town that cost that much and more: opera, symphony, events at the new Mondavi Center, concerts, ice shows, etc. And a tivket to a movie costs darn close to those $10 Arco seats. So can I afford season tickets...heck no. CAn I chose to go to a few games every year...heck yes. And $10 for parking would be considered ridiculously cheap in a good many places in CA (Try SF

).
