We booked this cruise via phone call and we were informed by Petros, that we begin at 15:00 from Vlyhada or Oia and go back at 20:00. We began from vlyhada and they came to pick us up from our hotel and made 1 more stop to pick up a couple. We were 7 people in that cruise. The program we knew was; start from Vlyhada marine, go to red beach, white beach, black beach, hot springs, thirassia, oia (and they said that we would stop in every spot) and go off at Oia and return to our hotel with the van. When we arrived at red beach, the captain said we won't stop at red beach because there were too many boats and it was crowded. When we arrived in white beach (about 16:00), because the depth is quite a lot, I saw the other catamarans that had their ropes (remezzo) and we had one also. We were in the sea, for about 10' after arrival, when the host told us that we had to leave in 2' because the fishing boat which's the rope was (!) was coming! So, we reached the catamaran and left! After that, in 10' we arrived in black beach (about 16:40), with amazing black stones and all that, but we didn't stop because they told us there was no place to stop, so we only took pictures and left! Then, we started sailing to Hot springs which was quite a lot and reached Hot springs at about 17:20. We had almost 15' there and left to go to Thirassia. We arrived there at 18:15. Amazing place, amazing waters. We had a swim as the captain was cooking. Petros, on the phone, had told us that the menu contained, salad, BBQ, shrimps and oysters and some more appetizers. Unfortunately, we only had chicken and steak, which is quite odd when you're on a boat. When we finished eating, I asked the captain how much time do we need to reach to Oia and he told me almost 5 hours (!) and that we don't go to Oia as we were informed! So, we started our way back to Vlyhada. After all, we enjoyed the experience as an experience but not the services. The crew was happy and communicative. I don't know if it was an unfortunate moment of the company, so I don't know if I recommend. I believe it was NOT a value for money.
