I'm getting married beginning of Feb this year and am arranging my own Hen night. The plan is to get a minibus to a nearby city for a night out, possibly stay overnight or get minibus to pick us up about 2am to take us home.
So far I have around 11 friends that are definately coming, minibus seats 13. I received a text from one friend today advising me she has invited a friend of hers that I have met once. Ok, great I say, as I got on well with her on this one occasion and my friend deosn't really know any of the others invited.
About 20 minutes later I get another text telling me 'we' really need to sort out how we're getting there and how many rooms we'll need as she has another 6 friends that really want to come 
I have no idea who any of these people are, but this apparently is ok as they are 'all really nice people, I wouldn't invite any troublemakers!' 
It wouldn't have been quite so bad if she had asked if she could invite some friends to maybe bump up the numbers but before she'd invited them not after! (I would have said no to this anyway as I think 12 is more than enough!)
She finishes with 'It's up to you'. Well obviously, what with i being my Hen night and all.
So, wonderful Mumsnetters, how do I reply?
