If you want to go up, you have to wait in line for 2-3 hours until you're through with security check and bought a ticket, which is quite expensive. Because I'm not 25 yet, it was only 12,50 for me to go to the top, for people older than 25 it's 25,50 which is way too much.
You drive up in an elevator and the view is nice, but the magic is done after like 10 minutes.
Going up by stairs is probably more fun.
