Celestyal Olympia is a very old Royal Caribbean Ship, that is now operated by Celestyal. Background is that I had my honeymoon on this ship, when it was the Song of America in 1990.
It leaves from the Port of Lavrion near Athens, and not in Rhodes. This form did not have the cruise port listed. This is a small port, with a parking lot next to the ship that is well below the cost of a USA parking garage. A short walk to the cruise building, where we had our first encounte with staff. My wife being in a scooter, they came out to us, and once they found out, we were in one of the very limited balcony suites, they immediately took action, our luggage, and skipped all the lines, which was not very long to start with.
They have a shuttle bus to the ship, but the walking distance is not far, and with a mobility scooter, we just walked. We were welcomed and went to the pool deck, which was where the suite entrance was. Note we were booked on the grandfather rate plan, so we had a beverage package and with a small upcharge, it was unlimited for a small upcharge. We had our first drinks, since boarding started at 9:00am, which is very early for a cruise.
