F23
I was just booking some tours for my trip and came across the coupon. Might be useful to anyone who has taken advantage of the cheap US/Canada flights that have been on here lately and certainly helps ease the pain of our exchange rate in the US.
They say that it excludes some tours, but everything I've tried so far has worked. While it says you need to use the mobile site or apps, using the mobile site on your PC works fine if you don't mind the weird looking layout.
Happy booking!
