Hi Janet,
Well, first of all - welcome to the world of solo travel! I'm sure as you look through the community you'll find words of reassurance from our members that will help you take that first step.
For the Pompeii, Sorrento & the Bay of Naples tour the current numbers are;
16th September: 3 travellers booked with ages from early 20s to late 80s
23rd September: 2 travellers booked with ages in early 40s and early 70s.
With a number of months before these dates depart, these will change so please feel free to ask for updated.
Kindest regards,
Julia
