Need some advice from the PRO's

So i've been really wanting to go to Bimmer Fest ever since i bought my BMW. So this year my new years resolution is to do it, but what i want to know is how much much does a trip from the Bay Area down to LA cost for other members from the Bay Area? What i want is like an estimate of how much i should save up for it. I plan on driving down there and staying at a hotel for 2 nights. For the hotel i can obviously check myself but all the other expenses i need an idea of how much it would be. Also before i forget is there a drive down there where alot of members drive together kind of like in a pack? Any response are welcome and thank you for tsking the time to read this.
