I'm taking my first cruise to the Mediterranean on NCL Gem. itinerary: Rome, Naples, Taormina, Zakynthos, Alexandria, Port Said, Ashdod, Limassol, Rhodes, Kusadasi, and Istanbul. I'm looking to book some private excursions through Viator and others in several ports and trying to figure out start times. When it says the ship will be in port for example 8am-7pm, is that ship time or local time, and what time should we book our excursion to start, 8am, 9am, 10am? Thanks
