Price is awesome but expect that “guiding” is minimal. Basically you will be meeting the rest of the tour at the designated location then take the ferry to the first island, stay there for 45 minutes, then the second and the third for each 45 minutes, then back to your pick up point. If your pick up point is at the train station, the tour is 5.5 hours. If St. Marco, 4.5 hours as this is the last pickup point. Glass factory show is awesome on the first island. Second island is the colored huts which we think we can spend more time. Third island is the heritage site which we think the guide should do more explanation what they are. Site is awesome though. Overall for its price, you get what you asked.
