Yes, and no guilt attached to this desire either :) I'm a mum of three small boys, and I have just been away for a week to Barbados (it was for my brother's wedding, so I wasn't alone alone - but I was without my kids and my partner). I barely thought about my children, and when I came back I was recharged and ready to enjoy my time with them again. It's not something I'm going to get chance to do very often, but if I get the opportunity to go on holiday truly alone I will seize it, definitely. Alone time is precious to me - some people don't need it, but that shouldn't mean that those of us who do should feel guilty about it.
I do eat in restaurants alone, and go to the cinema alone. I love it. Total freedom!
