Hi we went on our first Saga cruise (Canaries) last year. We are early 70s. There were a lot of people older than us but many more were younger. We met a lot of solo travellers onboard who, without exception, said they were having a great time. There was a solo gathering early every evening which was well attended.
By the end of the cruise I had decided that I would definitely cruise as a solo with Saga if I found myself in that situation as I know I would meet nice people of all ages, be well looked after by the staff, and, importantly, I would feel safe.
i’m sure you’ll have a great time in Norway. Please report back after your cruise.
