there were 5 of us in our car last year, and it cost $10 per person last year DQ, so i would budget for $15-20 each way max this year. At this stage it's just us three, although that could change.
As stars said, there really isn't much you should need to buy, just food and possibly chip in for a tabogin or whatever. There should be a few of us not skiing, sothere's no problem there.
And, as some one is bringing sthn comfort, and we're having a cocktail party, that means that you shouldn't ned to pay for any grog, as it's already been paid for with your ski money.
Food and transport. that's it.
As for the alcomohol, so far i have:
bailey's x2
bacardi x2
vodka x2
The reason we got 2 bottles of bailey's is for cocksucking cowboys. Everyone loves them.

We're also intending to buy some tequila and some kaluha. Teh rest of the money will be spent on juices and fizzy drinks. That will bring us to $260.
We were thinking that, seeing as we've covered everything except the schnaps bottles, could each car bring a bottle as well? Flavours we will need include:
-Chocolate
-butterscotch
-caramel (?)
-advocat (for creamy drinks)
and my car can bring blue curaco and grenadine.
Is that cool? Thoughts?
