We were on the 10/26, and as Sue ellen said, the pool was closed twice that I saw for clean-up, and once on a sea day. On the western when there is one less sea day, this made a big difference.
I never saw a CM say anything, but there were signs and notes in the navigators. There were CONSIDERABLY fewer babies in the mickey pool on this cruise compared to our last cruise. I think parents were being mindful of what was posted and what they read. THere were a few babies held by parents with their feet in the water. Saw no swim diapers. There were some young'uns playing in the ears, but these aged children wouldn't have been in the face part of the Mickey pool anyway.
There was one other time when the pool was open, but the ears and sides of the mickey pool had no water. I assumed this was a result of a clean up.
