None of the bus routes go directly from the Orleans to DT---at least none that we could figure. So, you would have to make a transfer. My first thought would be to take the east bound 201 to the Strip and then catch the WAX at NYNY---but the WAX only runs every 45-60min depending on the time of day---from NyNy it hits the interstate and heads directly DT. But you could also take the 201 and then catch the SDX at MGM as well. You could also ride the Coast's shuttle to Ballys and then catch the SDX from Paris. None too convenient.
