*Incidentally, a 1 or 2 weeks pass are of course cheaper than a "3 weeks pass" while a month's pass [or longer] is more expensive.

But even in 3 weeks, you'll end-up going to more than 20 tourists sites since there's so much to see here in the U.K. (In fact, we saw 20+ sites in 3 weeks!)

And so, if you do the math, 20 sites x $20+ = $400+. Thus, you'll really saved a lot of money with a pass which in our case was: the $150 "3-weeks pass."

**But one pass is good for only 1 person unlike in the U.S. where one pass is good for the entire family!
