I feel like an idiot, but in the Personal Information section of the official site to purchase Colosseum tickets there is a drop down list to choose "Nationality" and I cannot find anything to indicate U.S., English, or American... It is a mandatory field. What am I missing here?
I had this same problem when purchasing tickets last year! It's "Stati Uniti" (United States in Italian). I actually ended up selecting "Isole Vergini (USA)" at first because I couldn't find the right one until someone pointed it out.
Hope this helps!
God Bless You! That was what I needed!
Your welcome!!! I wish I would have known that when I ordered tickets :)
