COMMON DIFFICULTIES ENCOUNTERED AS A TOURIST
First, see the information about changing money and using credit cards. Any credit or debit card with a VISA or MASTERCARD logo is the best thing to carry. ATM cards are not universally accepted.
Then see the section about telephone service. Telephone services in Europe work quite differently from the US -- we are spoiled with excellent service and integration, Europeans are just learning about this.
I will expand this section, I started to write about using telephones and it became its' own page.
For now ... Just Don't Do Madame Tussaud's Dumb Wax Museum. There are so many better things to do in Amsterdam, you will just be wasting your time.
