N.B.
We went on a Disney cruise about 8 years ago, just the short 4 day one. Unfortunately I got influenza tha last 2 days and flew home sick (great way to end a vacation..we did our own 3 or 4 day "land" part at some of the disney parks first). We were traveling with my in laws and nephew they raise.
So MIL, FIL and then 10 year old nephew as a set, and me, hubby and my 8 year old daughter as a set. On the cruise ship (I think it was the "Wonder"), we had mid ship, balcony, adjoining rooms. Each room had the couch that magically became a regular sized twin equivalent bed for the kids to sleep on it each of our rooms (I say magically as the cabin peeps transformed it all when we were out during dinner and the evenings full stage shows we attended).
We LOVED the balcony. It certainly helped with my well known motion sickness and we loved waking early and sitting out there as we pulled into the ports and seeing the other ships side by side with us and waving to other dock workers, etc. The kids LOVED it. It was actually a peaceful and calm part of our days before all the fun chaos of the cruise day.
Our adjoining rooms came in handy during awake hours when the kids played, watched a tv program together while us adults got ready, etc..so we could be chatty and excited together about the ship, but then since we WERE still seperate parties (and my FIL snores soo horribly!), we shut, but not locked them at night. My dd woke early one morning...REAL early like 5:00 am and we were generally waking about 6-6:30 to watch the pulling into port thing...but she later told us she heard Grampa next door and smelled his coffee, so she just went into his room (remember we did not lock the adjoining door!).
I woke to find her gone, the door partially open! I went to the balcony as my dh suggested before panicking , and there she was, on the balcony next door with her Grampy, having a nice quiet morning! Scared me there for a bit, but I knew she wouldn't go anywhere as she was not a wanderer and scared of her own shadow.
So for us, that all worked out. We booked with adjoining rooms back then, mid ship, balcony rooms. We did it all on purpose to suit our needs. Other than me getting sick and having to deal with other peoples kids (who were rude and many were bascially set free to misbehave and not be watched), we DID have fun and I wished we had done a 7 day cruise.
Have fun!
