My widowed friend has just come back from a cruise around the U.K. sailing from Southampton, she went on her own , the were also the opportunity while on board to meet up with other “singles “ which she did , she says she really enjoyed .
A few years ago my partner didn’t want to go on holiday so I’d booked a “ single traveller “. coach trip to Lake Como , Italy , with Ledger which were good .
Also, there is an online traveling group called Goldies Holidays , I've gone with them couple times , once to Malta and then to Spain , everyone in the group books their own holiday independently then meet up at the chosen hotel .
When they say “ singles “ it doesn’t actually mean people who don’t have a partner, it’s for anyone who have their own reasons for traveling alone .
Personally, I don’t mind actually traveling on my own but as long as there are others likeminded in the same group . I’ve made some nice friends from the ones I’ve done and can be a lot of fun , so, book up and enjoy a well earned break .
