Just putting in my 2 cents on how our cruise went, since I read each and every one of these before we went. Hopefully it helps someone. It was my inlaws (in their 60's), me, my husband (39) and my daughter 10 and son 6.
We stayed at Disneyland before our trip, and used Super Shuttle to get to Long Beach. Picked us up at noon, was at the pier by 12:30. The line was long, but once the dome opened, the line moved smoothly. We were on the ship by 1:15, so it wasn't too bad.
Our room was mid ship, and it was very nice to be able to go down 1 deck to 5 where a lot of things were, and up to the Lido and Camp Carnival where my kids were at times.
We had a quad balcony cabin. An upper bed, the couch turned into a bed, and a king size bed. It was comfortable, but you could feel the "seem" where they were connected. So you'd hit the seem and roll back :-) 3 big closets for clothes, but the life vests took up the last one, so it was really only 2. And the bathroom was small, but surprisingly we never once flooded the floor from the shower! Talk about luck!
There was only 1 night where I could hear the music coming up from the floor. No one else in my family complained, so I just used earplugs and it drowned it all out.
