I am 62 and have travelled alone since my divorce 10 years ago. It can have its plus side.
Able to do what I like.
Meet new people.
I tend to cruise as you don't feel odd going to entertainment in evenings etc.
You must try and make an effort to talk to people, if they don't respond it's their loss. Most people are very friendly and helpful.
Had one of my best hols ever last year with P&O . On a dining table with 7 other singles age range 44- 84 we had a whale of a time in the evenings but I was free to do my own thing during day .
Don't give up
