Have a close group of friends and a wider circle of acquaintances. Have always holidayed with our friends especially when the children were all young, fabulous memories.
One year our D and our friends D fell out at the airport, avoided each other round the pool for 2 weeks and made up on the bus from the airport to the carpark back home. Fortunately H and I, friends and the brothers thought it was hilarious. We often bring it up just to "embarass" them (isn't that the job of a parent?). We know holiday with just us oldies, still have fun.
We have had long weekends with acquaintances and had a good time.
I am generally easy going as is H, and the 2 couples we holiday with are also. If there is something someone is desperate to do/see then they do it, sometimes it's us, sometimes the women and sometimes the men do their own thing. Which makes for interesting conversations over dinner.
When we have been self catering the only rules are the men cook!!!
