I'm not aware of any plans to add Chile to the Just You version of this holiday. But we currently have a very interesting thread on the Community where members are suggesting holidays Just You could add in future. You might like to add your idea there. The link is:

Argentina and Brazil looks a good trip but I've noticed that your 'mother' company Travelsphere do the same trip but go to Chile too making it a 14 day holiday. Is there any reason why this isn't available to Just You as I know there isn't just me asking this question. I'd love to do Chile as well but the hefty single supplement puts me off from booking with Travelsphere. Are there any plans in the pipeline to do the same trip for the single traveller with yourselves?
