I don't remember the name of the companies, but it was from Leros to Rodos (Katamaran) and from Rodos to Kastellorizo (big boat) and from Kastelorizo to Kalymnos (big boat, with one night trip) and from Kalymnos to Leros (Katamaran). The trips were quite good, only the first trip was in late about 2 hours. The night trip was really nice like a hotel! Your service was also great, got the tickets at home only 5 days after I booked them online.
