the location is very confusing, im talking as an experience traveller lol, need to asking many times as the location for redemption moving from 1-18 to 20flr. :) and the elevator to the 81 floor very long and queing as they very slow and only operate some elevator, quite scary to be honest, because sometimes the elevator just stop and beeping. i know its and old building, but the view is stunning, try to choose outdoor buffet because indoor will be nothing special. For me this just 1x experience would not going back. but the staff and all is very good.
