I haven't stayed at POR before, but we did stay in a suite at AoA. Our kids loved it! The zero entry pool was great for the little ones, and the Finding Nemo splash area was a big hit. Another good thing about the suite was the microwave and kitchenette sink rather than just a bathroom sink. It makes it easier with the little kids. We really enjoyed our stay there.
Now, the suggestions to stay in the Royal Rooms because you won't be able to in the future do make sense. It all depends on how much you would like to be able to do that. Also, taking the boat to DTD is really fun for the kids in itself. And very convenient.
Have a great trip!
