Patrick - so you know 1 ticket for 10 bucks is for the "couple", so unless you are bringing other girlfriends instead of just one, 1 ticket is enough.
If on the otherhand, you are bringing more than one girlfriend thus needing more tickets

, having each girlfriend bring a sald or a desert would be cool. If only one girlfriend - I think a simple desert would be nice
Did you get my e-mail the other day?
