I'm addicted. I have to go every year. I would give up other cons first before canceling SDCC. Of course, I live in California and drive to San Diego, so that does lower my costs as compared to someone who must fly.
It is terrifying how much cost of living has increased, for food, energy and other things. Travel costs are high, and don't seem to be coming down anytime soon. If you do not attend, Darqamin, I will miss seeing you there, but with such a distance to travel, it is understandable if you would want to stick closer to home for your cons.
