Mud baths - by coach?

We are going to Icmeler 21 July. We have been to the mud baths twice already, but as someone new to turkey will be with us this year we would like to take him too. Last year we went by boat trip from Marmaris, but wondered if there are any trips bookable to go by coach rather than boat, found the journey on way back too much after a long day - too cramped, too hot on the boat.
