Santorini was a superb experience, we did our own thing and had a very enjoyable day. Went up & came down by cable car which was good (4 euros per person each way).
Once again did our own thing but not a pleasant experience owing to far too many shop keepers etc... trying to sell their wares constantly in your face!!!
Once again did our own thing and found a small beach just around the corner from the port unfortunately it got rather crowded as the morning went on. The shopping area was quite nice to stroll around with nobody nagging you to buy something.
