Spent lots of time waiting and standing in line going up. Worth the wait but I wish it went a little faster.
Very nice view over NY! Book it before, so you got a fast entry.
The view from The Top of the Rock was amazing, we went at night so the city looked dazzling. Don't turn up early and expect to queue as they send you away again until your tour time then it's a free for all to get in. A bit of hassle finding the place as no signs and even with your voucher they send you off to another shop to get tickets then back to where you started to queue up. Once at the top though the sights are worth the hassle.
