You definitely have to go at least one time, it's an amazing & intense experience. This new 1WTC is currently the tallest building in the nation & has some of the fastest elevators in the world! You go up over 100 Floors in less than a minute! There's a fine dining restaurant located on Fl 103 & OF COURSE the view is amazing. I've been twice once during daylight hours with my wife & kids. Then I went once w/ a good friend during the night & the city was lit up like Las Vegas. Keep an eye on my blog I'll post pictures soon!
