I go with my wife.

We pay about 300 for a room at the plantation.
We tow the car so gas totals around 350 including what we put in the car.
Ive heard people who just drive thier cars there pay around 200.
Racing can cost up to 90 and to park with the group you have to be a racer... Even if you dont end up racing... And wanna just be part of the group. There are a few that do.

Food is what we normaly spend anyway.. Altho we eat out quite a bit.

We consume alot of booze so keep that in mind.

And its hard not to be there all weekend and not spend money on tshirts and parts.

We try to budget each year... But fail and spend more then we should.
