If you mean Barbara and Colin from Manos holidays, you can contact them via Symi Tours. Or you can email me at the Symi Visitor and I will deliver your email to Barbara - I pass her most mornings on the way to work. You'll find our email address on our homepage.
That sounds like them. Colin was with My Travel when we were there and they were both incredibly helpful. I`ll try Symi Tours, but if you could mention to Barbara that we`d like to get in touch, Elaine and I would be grateful.
