The 2 for 1 site lists them at 26. The Fast Track price is 32 (x 2 people would be 64!) I've read that as long as you have your ticket in hand (purchased in advance online) there's not too much of a line for the eye. True? Or is it worth the expense of a Fast Track? We are not in a hurry.
We're not buying the London Pass. We don't want to feel rushed to see everything it includes.
Also, the U.S. dollar to GBP is pretty bad right now too, so hoping to save where we can.
