On our first trip to NYC we were determined to see all the sights and do all the tours. We were advise to do the Empire State Building at night and the rocker fella during the day. I didn't really see what all the fuss was about. I thought the views were a lot superior from the Empire State Building. Maybe we just should have done it at night. The one good thing is you can see the Empire State from the rocker fella. The actual building is beautiful and there's a nice wee tour on the way up which allows you to find out about the building and the history of the building and owners. Was very interesting. Also the lift on the way up is interactive with a movie being played above your head. Very cool. We purchased a combo pack which allowed us entry to top of the rock and also entry into The MOMA which was good value. Think it was $50 in total. I guess it just depends on what you are looking for but. Personally thought the Empire State Building was a lot better.
