Viator is offering discounts on some of their quick 2-day trips from Athens to the islands of Mykonos and Santorini. Through October 31st, travelers save 10% off the usual prices for either first-class or tourist-class accommodations, plus transfers to and from the ferry and the ferry journey itself. Meals and other activities are not included, though the hotels generally offer breakfast.
Could a reasonably enterprising independent traveler do as well price wise on their own? Probably. But if you like the comfort and convenience of letting someone else make sure your connections are solid and that you have a nice bed waiting for you at the end of the day, this can be a great way to squeeze in another island on your trip to Greece.
