We are senior aged 65-70 and interested in visiting historical sites, old ruins and enjoying beautiful scenery. As we don't drive, we have to walk around using buses and taxi locally. Although we think that this is not too long based on this itinerary, some say that we should add Mykonos shortening staying in Crete, Santorini one or two days each.
Now we would like to hear your valuable opinion which is better. Any kind of your advice will be appreciated, for example 3 night-stay in Oia is too much and so on.
Thank you for your help to make our trip fruitful, in advance.
