Hi klb68
we went to Peru last year with Travelsphere really because it was a much more comprehensive tour, JY do seem to skip on certain tours, our group was mainly couples but there were 8 of us singles and so at least 5 of us grouped together as some singles do prefer to go their own way, naturally the choice is yours, if you ask the moderator he/she could tell you if there were any other singles already booked on the tour before you decide to book
hope this helps
