Hi Gin
I will pass on your comments to my colleagues - perhaps this tour will make a return in the future? I know that people who have been on this tour were very positive about the experience so I can only imagine that not enough people were booking it.
The Travelsphere version of the tour probably isn't ideal for you because the majority of customers do travel in pairs, as you say. But there are usually a few single travellers on these trips as well and you would see many of the same sights. Perhaps you and Karen could travel on the same trip?
Kind regards,
Olly, your editor
