We were concerned about sharing the room with our teenagers. We're looking at the Radiance for Alaska next year. Some of the pictures with pullmans look like the pullman isn't above the sofa, it's actually above the main bed which didn't appeal to us at all. In another picture, I believe it was an interior that slept 4 they had a trundle - but it was actually under the main bed, so to sleep 4, the main beds were required to be seperated with the trundle in between them and then one person slept on the sofabed.
Those configurations didn't work for us, so we looked at booking 2 interiors, which was cheaper than 1 balcony, slightly more expensive than one Oceanview, but very close. But instead we stumbled on to a family oceanview - there were only 6 of them on the ship (ours is room 8000) on the ship. It has a tiny seperate sleeping area with an actual twin bed and a pullman above it and then a bed and a couch in the main area. This was the most expensive oceanview but still cheaper than a balcony. I think we'll appreciate the space, but there is still a part of me considering the 2 interiors just to get the second bathroom.
