We chose this 'taster' three day cruise to see what the new Harmony of the Seas was like. It was advertised as the largest cruise liner. We had been on Oasis of the Seas and did not expect there would be many differences (Except for a few inches in length) but we found the twisting tube runs fun, as something new.
The ship was really not ready to sail. There were workmen (mostly French) all over the place trying to fix things or get things to work for the first time.
Only a few people had magnetic 'Do Not Disturb' and 'Make up My Room' signs and none could be found by our room steward for us or for others nearby. Consequently, he had to knock on the door to see if it was convenient for him to come in, which was irritating.
Good walk-in wardrobe. Very many drawers. Nice layout.
No excursions taken
