I saw that post too in FB.
Have to say, I am unhappy with most of the changes. I think it is shame that they are going to take away the port side of the observation lounge for additional cabins. And will these be Haven cabins? I think Haven cabins are already at a high level and will make the Haven more crowded.
Additionally, they are taking away two spaces which, I think, appeals to families with teens, the Galaxy Pavilion and Laser Tag and they both now will be venues with an over age 18 requirement.
I do understand that many people will be happy with a Thermal Suite. I also think that with the Vibe being on both the port and starboard side, they additional Vibe space should be allocated to a regular old fashioned sundeck including in one's cruise fare.
