Reviews: Kos: Glass-Bottom Boat Cruise with Mermaid Show
Guest User2026-09-20
The staff was nice. It was not overcrowded. It was not clear what is paid extra. The swimming was in the harbor and I did not want to swim there. The trip back was very fast so that we were hitting the waves with the boat and we all with all our stuff got wet. It could be improved but it was nice overall.
