I've been to all the tall buildings in NYC but OWO has the BEST view. Right from skipping the line, to the elevator ride, to the "intro" in the dark room (I won't give anything away, but I loved that part), to the observation deck, it was amazing. WE did not rent the iPads because we already knew a lot about the city and what buildings we were looking at, but it's a great resource if you don't. We were there around 1pm and the sun was shining right in, so we didn't get the best photos but it was still AMAZING. Fantastic panoramic views of the city and I would go back there next time, maybe at a different time of day to see what it looks like. We spent less than an hour and were satisfied with the timing. We didn't have to wait in lines either, which was great.
