California - Yountville Weekend House Rentals?

Does anyone know where I can find a weekend house rental for 6-8 people in Yountville? It seems that all the rental houses say "MONTHLY ONLY".

This will be for a friend's bachelor party. It's not going to be your typical let's-get-drunk-and-puke-on-each-other's-shoes bachelor party. We're more a go wine tasting, have a nice lunch with wine, more wine tasting, bed kind of crowd. :)

Thanks!

Napa County is very restrictive about weekend house rentals - basically you can't. So, if you want to do it, I would suggest looking on the internet and expect to pay cash.
