We were in this room our last
Disney cruise. It was spectacular! I also loved having the "flag room". When we were driving to the port, I mentioned to DH "There's our room, the one with the flag!" and he thought I was joking (yeah, funny joke ??) I told him I was serious and he still didn't believe me. Not until we got to our room. He loved that verandah! He spent more time out there than anywhere on the ship. We both napped out there a few times, it was so peaceful. I love that the hallway down there was always empty - seriously, we never saw anyone else. I thought the other rooms were vacant, until one night I was leaning on the rail and peaked my head around to see our neighbor's verandah, and they were sitting out there. Oops!
OP, you will love having all that extra room! It is wonderful, so relaxing, and beautiful! The sunset every night was my favorite. The first night we noticed some motion, but that was our problem all over. DD ended up being sick that night and missed orientation at the teen club, but she ended up really getting along with our tablemates and hung out with them quite a bit. Other than that first night, I didn't notice any movement at all. I've read complaints about soot and other stuff on the verandah, and we never had any issues. I also liked that our verandah had a roof. It kept the sun, wind, and rain away from us relaxing. We did a Princess cruise last summer and couldn't get an aft verandah. I was so disappointed, and the regular verandahs are so small!
