Me and my pals went on the 3 bay cruise. Our boat waas able to take around 12 people, there were 7 people on it. The top deck of the boat had sunloungers whish were great to stretch out on, relax and get a tan on.
Kefalos was a bit crap, shingly beach, not much to do.
BBQ was OK, salad, bread and souvlaki and wine if you wanted it.
We stopped at a cove and did beer diving (champagne bottles kept sinking apparently!) Captain of the boat was a great guy-hilarious and knew a lot about Scotland.
Bubble Beach was lovely-wish we'd spent a day there as well. Quite pricey though but a fabulous beach.
We paid 15 euros from a travel shop place. Well worth it I'd say, if even just for the loungers on the boat-bliss!!!
