The worst thing about going to the top of the Rockerfeller Tower was trying to find it. We trudged around for quite a while before we found it - even with a map.
Anyway, once we got there, there were hardly any queues and we got to the top very fast.
Views are excellent but the missed trick here is that there is no rooftop cafe or restaurant. I really don't get that. They advise you not to take any food or drink up and then, when you get to the top, there isn't even a drinks vendor.
Not good when you have a thirsty moaning child with you.
