Of course I have absolutely NO experience with this at all. If I were doing my place, as an electrician, I would run a separate line to each location. If you were to do a continuous loop then you would need a junction at each location. If you were to decide to use the point at the end of the run then your signal would depend on the connection at every other point. (not to mention that the entire run would be way longer than necessary even though I don't believe you would lose signal strength for this kind of signal. why take a chance)
Of course this is a non-validated opinion.
