A MacBook Pro, as its name will tell you, is geared towards professional users on the go. These computers are more suitable for those who plan on doing gaming as well as intensive video and photo editing, and need lots of storage space to store those creations. The Pros are also more flexible, since they have the ExpressCard/34 slots in them for anything you may need.

From what you provided, I don't think you need a Pro. The regular MacBooks are more suitable for travel due to their smaller size. Also, they're sturdier and can still handle quite a bit of photo and video editing if you maximize the amount of RAM in the machines.

I recently made the switch to the MacBook Air from a regular MacBook. I realized after giving it a lot of thought that it's the best one for me. I don't play PC games, am not a movie editor and seldom utilize my MacBook's disc drive. So having a very light computer while traveling is awesome.
