We chose Harmony of the Seas because it's the largest ship in the world, and we love large, spacious ships. Positive point to be made: we had a balcony room very nice bathroom; shower nice size with shower doors so water doesn't drain outside of shower all over the floor. Negative bathroom point: There was no magnified mirror for women to put makeup on (I've cruised at least 10 times and they all had magnified mirrors). Mirror above desk, too high and lighting dim for women who like to "primp" and put makeup on. Usually the steward introduces themselves the first day, we didn't see ours after the third day (she was very nice when we did meet her). Positive: pool area beautiful Negative: no one walking around to see if you wanted a drink. Lines very long to go down slides. The cruise director was nowhere in sight. The sail away party was disappointing there was No line dancing that everyone always enjoys on these cruises (ex. electric slide). Positive : Food was pretty good Negative: missed a deli to make special sandwiches Positive: Casino big and beautiful Negative: I'm a slot player, no incentives on this ship. I've been on ships where they would comp you signature dinners, bottles of wine, and cookies every night in your room. Positive: the shows were wonderful Negative: make sure you make reservations way in advance. Negative: Elevators!!! no matter what time or day of the cruise the elevators were packed and the waiting for these elevators were horrendous. Windjammer was always jammed constant struggle to find a table. All in all we were on vacation and had a wonderful. Hope you find this helpful.
