MONICA · Group of friendsITItaly "I took the trip with a group of friends and we saw some amazing places. The speedboat captain was very friendly and even took us for a fantastic swim in the blue lagoon. What we didn't really like was the part at the so-called island. There were too many boats around these poor creatures, who come to the surface to breathe, risking being hit by a propeller."

Ann · FamilyBEBelgium "We had really value for money. The organisation is very professional. They really want to give you a very relaxed feeling, no matter how busy they are. Our boat was running late and they gave a replacement with a private boat. Thank you very much, we had a lovely afternoon!"

Dirk · FamilyNLNetherlands "Excellent location to rent a boat with sunroof. A sunny bay with small beach, parking space and a short boat trip to touristic destinations like the shipwreck. After a testdrive with explanation of all technicalities, you’re off to take it slow and go for a swim or do some racing on the waves. You can pay by apple pay/card on location. Enjoyed every minute of the 4 hours. And afterwards it’s a short drive to the shipwreck viewpoint."

Connie · FamilyATAustria "I highly recommend Happy Days Zante. Great value for money, the company organises to pick you up from a convenient location in a small, clean charter bus. The boat was not over crowded and the sites visited by boat were amazing. This trip didn’t feel overly touristy, perfect for those who want to enjoy the sites without the big crowds. The stop over at the olive tree was also beautiful. We were then taken back to the original pick up spot. Amazing day!"
