Hi! after doing a cruise over the Mediterranean and the Caribbean, now I'm looking forward to my holidays over the Greek Islands :)
Since while doing a cruise you don't have so much time for sightseeing, I usually book the organized tours offered on the boat, but I always end up feeling cheated, losing time on a souvenir shop, or bored by an unmotivated tour guide...
I've heard about these "guruwalks" or "free walking tours", some walking tours where you don't have to pay anything upfront, just a tip at the end if you liked it.
Have you tried this kind of tours before? are they fun? well-prepared and professional?
