If you are talking 2 weeks monthly, and you are considering 2 people for the two split roles, you might end up travelling the whole time (or "just" 4 weeks a month :)).

Not sure if you ever travelled for a week or more monthly, but I did it for a year or two, and it was mentally and physically taxing: you are packing and unpacking constantly, you are missing family and friend events, and it's hard to plan and create family. Or settle in a new home. Or do any personal project that requires more than a month (from improving your bike to taking a cooking course).
