So we are being slightly unconventional. A lot of the wedding party is made up of our mutual friends. We both have guys and girls on our sides. Planning the bachelor/ette party has been tricky. What we have decided to do is head down to a casino as a group. We will spend some time together but then my fiance and two of his nerdy gamer friends can go hang out together in the hotel rooms while the ladies on both sides and I go dance in the club. Lots of outsiders have said that its an awful idea, but it works for us. The problem is, and I don't see any way to fix it, so I am just venting at this point, one of my ladies is 20 and so she can't go to the casino. It sucks and I feel bad, but we haven't come up with any other alternative that allows her to participate.
Re: Just venting...
In what state is this casino located? In California/Nevada, you only have to be 18 to be on the casino floor.
OP-you'll just need to say "Thanks, but no thanks. I want my entire WP able to participate in the entirety of this pre-wedding party. I appreciate your hosting, but I have to decline THIS offer."
You are getting married ONCE. You get this ONE TIME to celebrate your upcoming nuptials with your nearest and dearest. The party is about having fun with your friends-ALL of them.
Your "of age" friends are certainly welcome to go to any casino/club they want, when they want...just NOT for your pre-wedding party.
