We wanted to try out a large ship,and Harmony of the Seas did not disappoint. It was not too hard to figure out the ship layout. I was hoping to buy my two carry on bottles of wine at the dock. But there was not anywhere to purchase as past cruises. We did not care about the ports, as we have been to each of these stops several times before. The Royal IQ is a great tool for a ship this large to communicate with your traveling buddies. I liked that you had to use your seapass to turn on the lights. I always knew when my card was! I was not sure if l liked the idea of booking shows ahead of time. But once on the ship it helped make it a true vacation that I did not have to think about what I was going to do. Of course, it was no problem if you changed plans. The entertainment was great at all the shows. The shops on the ship were too upscale for my taste. Not all cruisers are wealthy. Don't waste your money on the Kitchen tour that is offered on a sea day. Only spent about 15 minutes in the kitchen and then another 1.5 hour being served the lunch. Time on vacation is too short to waste. Charging $2.50 for popcorn at shows & movie is tacky! The Ultimate Abyss is very fun, do it as soon as you board the ship, The rising tide bar and the bionic bar was not exciting. They both moved too slow. It was a great vacation and glad we traveled on the largest cruise ship in the world.
