Interesting point; travel does come across as rather unassailable.
By way of analogy: it's fine to take the first job you're offered and work there until you retire. If you took a new job, you'd have to learn new skills and deal with new coworkers, a new work culture. And should you return to your old company after the new one, you might try to incorporate skills, processes, or attitudes from the other place you found beneficial, changes which the old guard may not appreciate (but management should).
