We cloth diapered as well and did a lot of travelling when ds was a baby. We lived in Hawaii at the time so we did a lot of island hopping, an NCL cruise, plus several trips back to the mainland and we never did cloth diapers while travelling. Just too hard! Like the pp mentioned, we would switch the day before we left to disposables and get all the cloth washed so it was clean for our return. I can't imagine using it up until the time you left and having one of those sitting around your house for a week!! EEK!
We didn't have any issues with blowouts with disposables, but that was just our experience.
