I'm in a wedding party this weekend, and an irregular situation has come up. You gents seem sagely, so I need your opinions on what I should do.
Here's the situation: The groom ("Al") is a college roommate of mine, and one of his friends ("Ed") is organizing the stag party. My guess is dinner and some simple group activities (let's say chillaxing). A few of our old roommates will be in town, so I suggested inviting them. Ed has informed me that the B&G wish to set up a joint bachelor/bachelorette party, but that a few more won't hurt.
Here's where it gets complicated. My GF and I are both flying into town, and she isn't close to anyone in the guest list but the old roommates. She was only acquainted with the groom. I know Al would love to hang with the boys, but I don't want to leave my mathematical constant high and dry for the night. Considering it's a combination stag-hen party, my gut instinct was to ask if I could invite her, as well, but I have this vague notion that I'll go down as the guy who invited his girl to a bachelor party.
What the cluck should I do?
