The room was adorable and the resort is lovely. But the rooms are really far from the main building. There are no preferred rooms, all the LM rooms are far away. We requested a ground floor because we had kids in strollers. The pools are awesome and you can use any - Cars, Nemo, or LM. It was 5 years ago now, right after it opened. But I remember we didn't have any issues with noisy neighbors or noise from the pool. My daughter was 5 at the time and loved little mermaid, so she was thrilled.
I think you will like it, it is nice. The only issue is the distance to the main building. If you need a shorter walk, a preferred room at Pop or All stars might be worth it. If you're going to end up in a far section in one of those resorts, it's all the same.
