No, the top floor (level 10) is Bar Helios. The 9th floor is Club level. If you want a guaranteed highest floor park view, you have to book a "park-view room, Club Level".
Our room was on the 5th floor. This was the view:
It already looked fairly high up. I personally would prefer to be on lower levels.
I just looked at Helios pricing for the end of next month and all the 2QB rooms have the same cost under the AP rate. A park view room costs the same as a parking lot view. Strange.
