DD12, and I love Pop. We have stayed there in 2014, 2016 and 2018 and loved it all three times. We always get a preferred pool view and there is some noise at the pool, but once we closed our door, the noise never bothered us and I have never noticed hearing any neighbors. In 2018, we added a few days onto the beginning of our trip and stayed at ASMovies. I found it to be very nice. We were on the back side of one of the Mighty Ducks buildings. It was very quiet and it was just as close to cross the street and go to ASMusic's dining hall as it was to go to our own. We plan to do the same thing in 2019, but will have a preferred room at ASMovies and will again have a preferred pool view at Pop. All of our trips have been late May.
Our first trip was in 2013 and we stay at Port Orleans Riverside. Now, that was a quiet resort. We were near a quiet pool, so never actually went to Old Man's Island, the main pool, where all the noisy kids were. That trip was early May and was very quiet and relaxing.
I'm afraid that, while many of us don't find either resort too terribly noisy, as people without kids, you may just notice it more than we would. I remember when I was younger, long before having a child, being much less tolerant of the behavior and noise of children. Now that I have been through it all, even though my daughter was/is a very easy child, I have a lot more tolerance and patience for other people's children and their antics. I can also tune it out and not let it bother me. So, whatever that's worth.
