With regards to ages they do vary quite a bit on our tours. I had a look at this year's departures and we had ages ranging from 34 through to 80, with everything in between. That said, the largest cohort I would say are in their 60's.
With regards to other departure dates we do have a tour departing at the beginning of February, but it is already fully booked, and so the April ones are the only ones in the first part of the year that are free.
Hopefully there will be some people on our forum who have been on the tour who can give you their thoughts and impressions, but in the meantime you can check out the reviews on Revoo, the independent review site that we use:https://mark.reevoo.com/reevoomark/en-G ... trkref=RVR
