I have to admit I got suckered in to going to the top of the tower. It was $15 to go at night but the wait was over an hour! So I pony-ed up the extra $7 and got express tickets. The view from the top is pretty cool, it looks just like you see in the movies. However the observation deck is small and therefore crowded and it's VERY windy! The entire thing is surrounded by a cage which means taking pictures is difficult. Most of the people up there are cool enough to let other people in to take a look and it's definitely worth waiting to watch the fountains at the Bellagio. Overall it's one of those that you should do when in Vegas but it's not really worth the money and it's nowhere near as cool as the real thing!
