This was our annual cruise vacation, and we wanted to make it overly special by traveling on the Harmony of the Seas - currently, the world's largest cruise ship. I traveled with my wife and two kids (12 & 11).
The ship is massive, and was by far the king of cruise ships. The newness of all the materials, structures, artwork, and design was amazing. It is not that different from the Allure or Oasis, so don't expect to be blown away, but RC did give a nice facelift to the the whole ship design.
