kathand darren, you will probably find that in June you will not want to move far from the pool especially with the children, but Atlantis Waterpark they will enjoy and there is also Aquadream waterpark, which is also in
Marmaris and bigger. Both waterparks are great fun but have different slides to each other so 2 different days out and both offer a free pick up and drop off service (so hassle free). I would not recommend the children going on quads and I know the company that we use would not allow them on the quads so young even with adults. The jeep safari is a good day out, again I am not sure about the 2 year old as it is a rough ride and involves big water fights, however, some companies provide child seats to put into the jeeps if need be so making it a lot safer for the younger ones.
