Hi Mansel,
There are currently 14 travellers booked on this trip. At the moment you are the only gentleman on the trip - but this could change between now and when you depart in a few months as there are still plenty of places available. The age range for this group at the moment is early 60s through to mid-70s.
If you give me a nudge in a months or so, I'll give you an update on the numbers.
Kindest regards,
Julia
