My husband and I went to Kos Town in August. We decided to book on the Katerina because it had such good reviews. I would highly recommend this boat. The captain and crew are very friendly and welcoming. The food was lovely, and the entertainment was great. In fact we enjoyed the day so much we booked again for a few days later. Again we had another fabulous day and on the way to the third island saw dolphins!!!!!. We stayed at least half an hour while the dolphins swam round the boat. If you go to Kos make sure you book on the Katerina, you will not be dissapointed.
