Rip Off - do not book on website! - I booked this tour online and paid €60. When I arrived at the port I saw the same trip was €40 if bought there. I paid an additional 50%for the privilege of booking online!!! Also I had to pay an additional €2.50 City tax which wasn't notified. I contacted the company and they said it was tour operator costs - no refund. They said no one had complained before - I find that really hard to believe. Unless you like throwing your money away I'd suggest waiting until you get to the port. The trip itself is enjoyable and the islands are lovely. Under covid they, naturally can't provide snorkeling equipment but definitely bring your own. So worth it. Lunch was pasta with tinned tomato and slice of melon. Bottled water was a plastic cup with lunch. A good day out if you can get past the rip off.
