Choose the most expensive option you can find, and the smaller companies are best. Some operators just rely on getting customers tanked up, and really don’t care about what else happens. As a rule of thumb, if they have glitzy advertising on expensive sites, they should be avoided. The islands are definitely worth visiting, and the lunch can be superb - I’m still savouring the roast mullet I was given. A good day away from the bustle of Dubrovnik.
