That is tall!
Tallest we've been to is the Shanghai World Financial Centre.....I think that was about 1500 feet
We have a unit in Q1.....I haven't been to the top of it, but my family has, although we stayed on the 72nd floor once.
Can't say that I'm thrilled going up high....I'm a bit of a dizzy lizzy with heights. especially if you can feel them swaying!
I checked, the highest observation deck in the Shanghai World Financial Center is at 1,555'.
