Thanks for the suggestion. We shall definitely look at what is possible. We do currently have a pipeline of tours that we are working on, so it might take a little while before that filters through. I would, however, point out that there are generally a couple of single cabins available on each of the Mekong cruises with no single supplement i.e. at the same per person price that is paid by people travelling as a couple (so for example there are still two single cabins left on the 18th of January departure next year at £2999). Otherwise we have the Spectacular Nile cruise that is just for solos with departures in March and April next year.
But keep giving us suggestions and we'll see what we can do!
