Hi Jezzay,
It's not that there won't be single males, it's just that we already have our quota of single men. We're looking to host people in total and would like those numbers to consist of -12 couples, c.6-7 single women and c.5 males. Essentially the 'no single men' line is to discourage an overflow in my mailbox, and is still a regulation!!!!
Enjoy
