I went on a Solos holiday last summer when I needed a quick get away and was with a nice group of people of mixed ages (50's upwards). I was the granny of the group (!) but everyone was very nice. First time I'd done anything like that. I'd happily go with Solos again , and have since discovered lots of my friends do holidays with them. But there are loads of companies out there that cater for people on their own...hit the internet and see what you can find!
