Me again. Whilst in Crete we would like to do a day trip to Santorini. We are staying in Almyrida. Can you get ferries from Rethymon and Heraklion? We have a car so is it best to take car or leave it parked up somewhere before we go? Also any idea on cost? I would pressime as it is in high season that it would be best to pre-book. Should I do this in the UK or best to wait until we are in Crete?
