I've had the opportunity to stay in the 8th Floor Suites at the Sheraton, Madison, WI in the past, and was upgraded as a Platinum member again this last weekend. Here are some photos of the suite:
Not seen in this living room photo is a large sleeper sofa and two very comfortable chairs.
There's a refrigerator under the microwave.
The bedroom also has a chest of drawers, closet, and a comfy chair and TV to the right.
The best: soaked twice in the wonderful Jacuzzi tub!
All in all, not a bad deal for under $100 per night! Love being an SPG Platinum!!!
