I had the same problem. I sent the final email saying what I was booking and the deadline for payment and just went from there. We were a small group but they did all get on fine and I had a laugh. But it wasn't that magic hen night you think of before hand. Unfortunately you can't make someone arrange something for you so just make the best of it and ensure you enjoy it. The thing to remember is, your wedding is your whole life to you, but to everyone else it is just a day, which isn't even for a few months. Many of them have been there done that, and some of them will have children/things going on in their own lives which mean they can't focus on you all the time. I wish I'd realised that sooner and I may not have kept disappointing myself!
