My partner Raman & I were on this ship (Celestyal Olympia) for a 3 Days Cruise, as part of our Globus tour 'Iconic Agean with 3 Night Cruise'.
It was their first cruise of 2016 (March 11-14, 2016) & the weather was early spring, so guess the ship was less than half capacity, to our advantage.
We had upgraded our indoor cabin on deck 3 (ic) to the balcony suite (sb) on deck 9 by paying a hefty sum, but it was worth every penny. We were in room 9003 (named after Vasco da Gama, who was coincidentally the first European to sail to India, the country where we stay).
