yep, so were we,
I think the problem for her was it was a gathering of friends that had been very close at one time, which she was a small part of, a group who use to spend a lot of seriously fun leisure time together, climbing, mountains mashing surfing, festivals ,
even though the point of the get away was messing about on cliffs, in sea, long walks, drinking, loud music, she was very determined to come, then didn't leave when it clearly was not the place for children.
we later found out her DH wanted to take part in a gaming weekend,
One of the group now live in NZ, another is overseas, and most of us are scattered about, with very busy lives, I doubt we will ever have the chance again.
I run a lot of family camps, group activities, I have spend nearly all of the last twenty summer (even last year)in a field by the sea, doing coastal things with a massive pack of children,
it is really annoying when people put you in the position of being the bad guy on the very rare occasion you have grabbed the chance of being child free, and decided to use that time doing something that is different, over the last twenty two years of parenting there have been years on end when we haven't had a break from children, so when we do get those chances we relish every moment.
I think it is a very mean thing to do, to even ask.
