The East Pool was never designated a quiet pool, it’s just what many call it. It even had a water slide for a short period. The new Oasis Pool is an oval like the old one but larger and in a totally different location. It actually sits where the old bathrooms and showers were. So they did not go cheap. You may consider it boring but they spent a lot of money on this new pool area.
I think they did a nice job. It does have zero entry and there are bubblers in the water at the shallow end. I think it goes to just below 4 feet deep at the deepest. Disney will not allow deep pools to be constructed anymore which is why the East pool was made shallow in 2011.
