Yes you can get a Bus from Marmaris to Bodrum, The direct one takes 2hours 20 minutes ask to get this one as if you dont you will get the non direct one and have to change Buses 3 times, lol, approx cost will be around 20 Lira, You can book it from just around the corner from the Big Tansas supermarket right beside where the Dolmeus terminus is in Marmaris, Ie walking away from the beach pass tansas take the first opening on your left, The bus kiosk's shop's are just as you go left.

thank you so much - means we can now get a one way to marmaris and a one way back to Kos from Bodrum - your a star
