Tours?

I just found this off their main web site: Guided tours in the Amsterdam Arena Ajax and the Amsterdam Aren A will be glad to welcome you for a guided tour. Especially for all foreign people, we organize one-hour tours, English spoken. I think that is pretty nice. We plan to visit family in the UK, and I have always wanted to travel NL, I didn't really think sports places held tours, maybe its more popular outside of the US? Not sure, but it is worth checking out. I would call and check their rates, but knowing my luck I would end up getting someone that didn't speak a lick of English.
