Oh goody, one more card to add to the pile. But yes, the AmEx should always be included. They were priceless several years ago when I was 3000 miles from home and my wallet was stolen. They immediately sent money to me at my hotel, and *if I recall correctly*, there was no "cash advance" fee, just that amount charged to my card.

And I'll never forget the rep who gave outstanding service, kept asking me questions to make sure everything was being taken care of, even offered to call all my other credit card companies to notify them. (But I had to think about which cards I had with me at the time, and ended up on my laptop in the hotel lobby at 2 am looking up the contact number for every card. Lesson: now I put all the cards/account numbers with contact phone numbers - both domestic and foreign - on a piece of paper in my carry-on bag, in case I need to call them.

Edited to add: Now you know why I thought traveling with so many cards seemed stupid!
