Most Inspirational Moment
Hard to choose since each island was so different and beautiful in its own way. Prettiest villages - Paros; Most enjoyable and varied walk - Naxos. Sharpest intake of breath and "WOW" moment - the first view of Santorini's incredible caldera.
Thoughts on Group Leader
Thanos was brilliant. I'd agree with other reviewers who've commented on how hardworking and helpful he is. Obviously incredibly experienced and knowledgeable, but he also goes out of his way to assure the health and wellbeing of his clients (and will also rescue the occasional goat that has got its leg stuck in a wall!)
Advice for Potential Travellers
Take a wheeled bag/suitcase; there is an approx. 10 minute walk from the hotel to the metro in Athens, then you also have to move your luggage on and off the ferries. I didn't take one, and soon regretted it.If you go in the hot summer months, take a good hat, especially for Santorini where there is very little shade on the walk. The walks are relatively easy but a head for heights will come in handy on Santorini. There was one part of the walk that I struggled with because it was loose, slippery pumice with a sheer drop just a few feet away (but there is an "easier" route that you can choose to take if you are afraid of heights). Be prepared for small changes in itinerary and lots of time on ferries. Relax and go with the flow!
Suggestions
The only bit I really didn't enjoy was the very rushed evening on arrival in Naxos and that overall we had a lot less time there than the first two islands. However I do accept that this was in part unavoidable because of the ferry timings. Apart from that, this holiday was the perfect chill-out week, just what I needed at the time!
