Well, I've been on the London Eye, so when in Vegas for a night (work meeting), and faced with the the opportunity to ride on the World's current tallest Ferris Wheel it seemed a great idea.
The view as you are going up is definitely obstructed but once you get about 2/3 of the way to the top the view is amazing. I only had my iPhone to take pictures but got some great shots.
A few critical notes:
1) I wish the'd dim the lights for night trips. Would allow you to take better photos without the glare of the overhead lights in your pod.
2) I also think they should have looked into glare-free glass for the pods ... for the same reasons! (Can you tell I'm a photographer?)
