Let's go to see Paris, wake up in...

I am giddy with excitement right now - In just 5 1/2 hours I will be leaving to pick up 2 dear friends from the airport!! They have flown all the way to little o' Switzerland to see me and travel around. I swear I'm getting more visitors in the next few months than the whole time I lived in Iowa! Wonder why.
We are going to be traveling to Paris and probably Rome...can't wait to play touristy photography!!
Do you have an recommendations for either place?
