They've raised their registration fees a tad, because although attendance is holding steady, the number of hotel rooms booked has dropped.
Things brings up a good point about attending cons, especially ones in your home territory. Do I Stay at home? Or do I get a room?
All things being equal, I'd rather have a room. Though I'm not a big party guy, there's usually lots of people in the con suite in the evening and often there's late night movies or anime viewing. Also, I usually have stuff to work on and to sleep in and then get a good breakfast and start the day works for me.
On the other hand, I've driven from West Michigan to cons and conferences on the other side of the state and even down to Indiana for a day trip, if it makes a difference between attending any of it or not.
Then there's the other side of the financial coin -- hotels don't host SF cons because they like us. They are a business and they need to make money. So I don't mind so much paying for a room or GOOD hotel food, and with my leg issues the last few years, tipping well for assistance. It's part of the total cost.
On the other other hand, I was young and cheap once (grin), so I can appreciate that many can't or won't afford the luxuries. Takes all kinds to make a con. But I like the vibe of the hotel filled late at night with my people.
