Coming from Orlando, FL, I can definitely say that although we have the "largest wheel" the original, in London, has a Better VIEW with some historical sights!

You're able to buy the multi pass to take advantage of some other attractions on the River, but you can also by the stand-alone pass.

The view is great and if you have a nice, clear day -- some awesome photo opps of this historical city!

Can be a bit pricey for what it is, but if you plan ahead... You can likely catch a good deal on a variety of sites/vendors!
