Our family has stayed on deck 10 three times, twice on dream, once on fantasy. Each time we have been in the cabins with the extended balconies at the aft. There would occasionally be some noise in the morning from the staff setting up chairs, but this was rare. We are early risers, so it didn’t wake us. There was not noise at night keeping us awake. The most noise came from neighboring cabins which happens on any floor.
Our next cruise, we are back on deck 10, we love the closeness to facilities.
