This question is specific to the BUS system ONLY - I understand one cannot connect between the bus and metro systems so please do not address that when responding.
ratp.com says you CAN use the same t+ ticket (tickets from the carnet) to make bus transfers (connections) - ratp.fr, english translation, Discover Paris, T+ ticket, FAQ page, items 2, 3, 5, and 6.
However, in the Rick Steves Paris 2008 guide, page 28, second sentence, it indicates you CANNOT transfer between buses with the same ticket.
When addressing the issue that one cannot transfer between the bus and the metro, he warns travelers that in addition to being unable to transfer between systems, they are not able to transfer between buses, "...you can't use a single ticket to transfer between the systems - or even to tranfer from one bus to another."
I'm inclined to believe the ratp site, but am also inclined to believe Rick. Can anyone tell me (who's been to Paris recently) which information is correct?
Thanks very much!!
