I'm a youngish widow with a decent income, adult DC, so no ties.
I've had trips with DC and with various groups of friends, often around a shared hobby, usually just a few days.
I've also done solo hiking trips and joined small guided groups overseas.
I love my friends and really enjoy our short breaks, but I don't think I'd want a fortnight away with them. The solo trips are by far my favourites.
When I was telling someone about my latest plans, he asked who I was going with. I said just me and he was all "aww couldn't you find anyone to go with?". I didn't try, I live in fear of someone doing me a favour by saying they'll join me 😆
