I stayed in the Hyatt so was able to enjoy both the inside and outer view. The architecture is what sets the building apart, combining oriental details with art deco touches. For me it is the most impressive of the 3 adjacent towers. Inside it is a sea of marble and gilt. The. Jew from the hotel reception on 54 is possibly best as there are large picture windows. If you go to the bar on 89 it’s less clear and some of the views are obstructed.
I’m or sure the skywalk is currently available as it was never mentioned, not that I would contemplate it for 1 second!
