I can understand why you are tempted to bring a macro lens overseas. I'm an advocate of macro lenses, believing every photographer should own one. Macro lenses provides a perspective unlike any other lenses, and could potentially give you unique holiday images that sets you apart from all the photos you see on Facebook.
However, I do not recommend that you bring a macro lens overseas. The only reason to bring them is if you are an insect, toy, or flower photographer. But if you are an insect, toy or flower photographer, there wont even be this question in the first place. So as a shoot everything hobbyist, you are better off bringing a standard telephoto zoom like the 55-200 than a macro lens. You will probably miss more holiday shots if u use a macro than a 55-200.
