I do want to reiterate that the Cat6 room does not have a sofa or a little table. The floor space is much smaller too. The photos and descriptions on JC, MSC, and most other travel sites show the Cat6 room lumped in as the same as the Cat7-Cat12 when it is not. I assumed it would have the same stuff crammed into a smaller space (based on the JC and MSC promo photos). No, it had less stuff in a smaller space.
The room is totally worth the money. We saved 500 or so by staying in a Cat6 with all our mates just doors away. But it sucked to go in the room and realize some comfort items were missing.
Did you have a Large Balcony before? Cuz I never had a sofa in any balcony cabin I had on the Poesia. Personally, I didn't notice a difference in the size of the room itself in my cat6 balcony (balcony was def smaller tho), nor do I think anything was missing that I had in previous balcony cabins on other ships *shrug* as they say YMMV
I do agree, totally worth the money.
