We found out about the Harmony and booked before the ship was built as 561 days before sailing. We have been on the Oasis and Allure and loved all the neighborhoods and restaurants. The Harmony is a beautiful ship and the cabins are outstanding. I would not normally take time to write this but there are things missing that some of us enjoyed. There is no pool in the solarium so if you want to swim with no kids you are out of luck. They replaced it with a drip fountain? I have not been on a Quantum class ship and this might be the new design but there are no cross walks for the performers to perform from in the Royal Promenade. This was a mess as they tried to use two temporary stages raised barely over the crowd. They tried to dance between the two stages and it was impossible to keep the crown from filling the empty spaces. I really felt sorry for the performers as they was no way to have the normal performance in the Royal Promenade. The final thing missing was the old Concierge (Diamond) club over looking the Boardwalk neighborhood. They permanently moved the Diamond club to the bowels of the ship behind the Casino. It is the same location of the old overflow of the Concierge club during the past Diamond celebrations. The club is to small and the overflow now goes to the Comedy club which was used every night on my cruise. You have to vacate the Comedy club before 7PM so you can expect a move to a crowed Diamond club if you have late dining and do not want to use your three free drinks somewhere else.
