We stayed in 8602 a few years ago. The room is fabulous. Our neighbors was Cheese Please and his wonderful wife. Our room had two bathrooms. One bathroom had a large tub, but not a jacuzzi. This is because it is handicapp accesible, they needed the extra room to create a roll-in shower. Seems like CheesePlease's room had showers in both bathrooms.
My favorite thing was the veranda. It was large enough to hold a football team. In addition to the chairs, you will have lounge chairs and a full size table. The table is awesome. We had room service deliver breakfast to the veranda.
The one downside is that everyone can see you on the veranda from topsiders/beach blanket buffet. In addition, you can hear them move the chairs above you when they are preparing for breakfast.
As for the stairs - yes they do go to topsiders.
