MissC - traditionally it's the best man and the CBM that organise the hen and stag, however, tradition is more or less out the window these days!
I was going to arrange my own as none of my BMs were forthcoming, but thankfully, one offered to take over yesterday, so I've given her everything I've done so far and passed on the phone numbers of the other BMs - I've far too much on at the minute and I was getting stressed out about having to arrange the hen night on top of everything else.
If you are happy to do it yourself, then go ahead, but if not, delegate (or, do as I did and keep your fingers crossed that someone will offer to do it!!).
Have never been to Kilkenny so can't comment on that part - sorry!
