I had high hopes of the cruise on the Azamara Journey from Mumbai to Athens, and my overnight British Airways flight from Heathrow, and stay the following night in the Vivanta by Taj President hotel in Mumbai, were excellent. Unfortunately it went rapidly downhill from there.
The boarding at the passenger terminal was shambolic, and when I finally got to my Balcony Stateroom I found a letter from the Captain, Johannes Thysse, informing me that I would be unable to use my balcony or the open decks after sundown for the majority of the cruise. This was part of the security arrangements, and it was clear that Azamara had made these arrangements months previously but had not told any of the passengers before boarding. Since many cruisers, like myself, enjoy being at sea because it gives us a chance to watch the stars, free from the light and noise pollution of cities, I can only conclude that Azamara deliberately did not inform us because they knew we would not book the cruise if they did. I paid a considerable sum for the cruise and I expected full disclosure on the part of the cruise company; there was no disclosure of any kind.
The cabin was pleasant, with a decent sized balcony, but the bathroom, and the shower in particular, was very cramped; it was impossible to take a shower without ending up with the shower curtain sticking to me and water all over the floor.
No bath, tiny shower, convenient for lift and launderette.
Santorini is one of the most stunning places in the world; I have visited it previously and therefore had already done a full tour of the island. I would recommend doing so if it is your first visit; after that it depends on whether your interests lie in the archeology of the ancient world or it's beautiful architecture and enticing food.
We docked at Piraeus which is the port for Athens; you will certainly need transport into Athens if you wish to see the sights though Piraeus itself is a fascinating and vibrant place.
I simply had the transfer from Piraeus to Athens Airport which is some miles south of Athens and the route avoided central Athens so I saw none of the 'sights'.
