Depends on your idea of fun. If your idea of fun is doing intensive research (e.g. hacking) then you'll build experience in stuff you wouldn't have had the opportunity to fit in between the brainfry of 9-yuck hours. I've had this experience, and the landing was superb - when I returned to work I had skills that I wouldn't have had if I'd just bounced from one job to another. Things that made me better able to 'hit the high notes'.
