The enlisted Marines were allowed to sleep and live in luxury on their cots in the hold. In a rough sea, the cots came up off the deck
making it difficult to sleep and keep one's meal down. As you can see, we could play a version of shuffleboard to keep amused.
On the trip to Turkey we stopped in Lisbon, Barcelona, Monaco, Genoa, and Athens before landing in Turkey.
At one point, we did go to Istanbul (not Constantinople) thru the Sea of Marmara for a few days.
