Does anyone know if there are other reliable ferries plying the Mykonos-Santorini route? I could only find SeaJets (operated with SuperJet) & Hellenic (operated with HighSpeed5) & it seems SeaJets has a pretty poor rep on these forums. Hellenic has the 1 service arriving Santorini in the evening, I'd rather get there earlier.
Are passengers on Hellenic's HighSpeed5 allowed to roam about the vessel, go outside (are there outside decks)?
Am planning a trip in mid-Sep.
