We recently stayed in the Al Forsan as well ...

Room:
Got upgraded to a nice Executive Suite with 2 balkonies, huge sitting area, one bathroom with shower & tube and an additional toilet. Excellent relaxing stay for 5 nights. Turndown service was done quite early but this was no issue for us.

Lounge:
I liked the excellent service team. The breakfast was fully sufficient for us (I don`t understand why NoY wrote terrible but maybe they changed it already) only point was that they had no big variations during our 5 days stay but fresh juices every morning, salmon and fresh made Omelet. The evening offer was just perfect, nice wine, hot dishes, salad and desserts. We had several evenings with many people and it became noisy sometimes.

Hotel Overall:
Excellent if you have Lounge access and a reasonable price for the room; however you need to be aware that almost nothing is around. One supermarket in walking distance in the residential area next to it. The Airport is close but you need a rental car (or Taxi) for Abu Dhabi Downtown, the new Louvre and Beaches.
