I would think any of the "destination" movies about a place she's always wanted to visit might do it. For example, "Under the Tuscan Sun" always makes me want to go back to Italy (same with "Roman Holiday" and "Three Coins in the Fountain" etc), and there are too many movies about Paris to count. Get her to tell you about someplace she's always wanted to see for herself, and then find movies that show it off -- I think it's harder to find a movie that glorifies travel in general.
P.S. I actually secretly love "Eurotrip." Scotty doesn't know!
