Hi Jane,
I'm also from yorkshire (aged 53) and think these holidays are great done 5 with my 6th booked for october and thinking of doing another before then.
My advice is if you fancy someting go for it, I doubt you'll regret it and would say you are likely to make some new friends alongthe way.
Age range from what I've seen is Ladies vary from late 20's to 80ish while men 40's to 80. The majority will be in their 50's or 60's with ladies outnumbering us men. Never seenage a issue on these trips, had a good laugh with people much older and much younger.
go for it
anything else just ask
Mick
