Actually, I did think of a few things that might shave the costs for next year.
For motels: As soon as you find out where the next BotCon is, book early. Sometimes when there is going to be a big event in town the hotels fill up. This allows you enough time to search out a good motel and compare prices. It also eliminates last minute rushing, when you'll be tempted to take just any hotel availible even if it's steep.
For flight: If you look on Travelocity and some other sites, the earlier you book a plane the cheaper it is. The prices rise the closer to the date you are intending to fly. So book early.
Food: Buy ahead of time and bring it with you. Buy things you can eat without needing to heat up or keep cold, so that way you can take them along in the car without having to buy stuff along the way. Plus you won't have to worry about it spoiling and making you sick, especially if you are going to be on the road awhile.
Booze: As you said, that stuff you'll have to bring yourself or you will end up blowing a ton of cash buying it.
As a side note, before you book a hotel, ask them if they have trouble with bedbugs. Those critters have been returning in full force and you can accidently bring them home with you if you stay in a place infested with them. They won't give you a disease, but you definately won't like having them in your place.
I AM THAT WIERD FANGIRL YOU'VE HEARD OF.
