The boat has the best berth in the lagoon. There are enough drinks to buy on board and the food is freshly prepared. The toilets are very clean. Since about 90% had booked this tour including Gozo, they only spent 1 hour in the lagoon and were then brought to Gozo. You could either ride the 30min (there and back) or stay in the Blue Lagoon. Then we were about 15 people on board for the remaining 3 hours. The lagoon itself wasn't overcrowded either, as the other boats "park" away. After 4 hours the others were picked up in Gozo and they drove to the Crystal Lagoon for 1 hour.

You must be aware that even if you have bought a ticket here "with a visit to the blue cave" - then you have to pay 14 € per person to enter the cave. The amount is only required when you are there. It is not possible to pay in advance. I think Getyourguide should inform about this extra expense beforehand :-(

The tour is ok, would have liked to hear a bit more about the history of the island. Don't sit next to the loudspeakers. The optional blue grotto tour was an absolute mess, wouldn't recommend it (even the guide was somehow trying to avert people from doing it). The organisation was chaotic, as, after coming back to the harbour, another boat was meant to pick us up. There was no information on where to wait for it (there were also other lines for the ferries), the time of departure was a mistery, the people we were informed to ask didn't speak anything other than Italian. On the boat, finally, we had to wait indefinitely until the fishermen could pick us up in their small boats to take us 5 min into the grotto for ~30€. Nobody spoke English and they were extremely rude, groping, pushing, grabbing our arms (although we have an athletic frame and can handle a boat change) and yelling at us to sit on the bottom of the boat in a dirty puddle. No English possible except when asking for tips!
