We have done our own version of the jeep safari on recent years taking in Yaka Park, Sakklikent and a good beach, maybe petara or other one we find local.
Good points of DIY......No driving in a convoy with nutters, you can spend longer at the things you enjoy, (we used to find the Gorge too short a visit) and best of all no calling in for an hour at a petrol station while they wash the jeeps.
