It was a number of years ago both times, but I have visited Paris twice.
While prices have probably increased since then, neither trip cost me very much. My first trip occurred while I was flying with the Air National Guard and stationed at Rhein-Main AFB in Frankfurt, Germany for two weeks. A couple of buddies and I booked a weekend trip to Paris through the American Express office on base.
We had a great time and visited Versailles, the Louvre, Eiffel Tower and other places.
The second time was on a visit to Europe a few years later. I flew to Luxembourg where I rented a car and took a drive around France and Germany. I spent a couple of days in Paris visiting many of the same places as before. Not wanting to drive in Paris, I traveled to nice, but moderately priced hotel on the outskirts of the city and used public transportation during my stay.
Paris is a beautiful city and I expect to be visiting it again as I like it and my wife, who has never been there, wants to see it.
