The Club Belcekic Beach Hotel in Olu Deniz is very nice. It's AI and is near shops, also there is a small childrens pool, but the main pool also has a shallow entry from one end which increases gradually and lots of the younger children went in there as well.
I'm sure there was a kids club as well, but mine are too old for that kind of thing.
It's in the Thomson/Portland Brochures and web-sites.

have you a resort in mind as not stated you may get a faster response if you narrow it down

Hello Club Asteria in Belek is fantastic also Green Nature in Marmaris is also good both 5 star A/I

The hotels on Lara Beach, Antalya are all luxury 5*. They are fab and an added bonus - they are only 20mins transfer from the airport. Loads of shopping in the nearby city of Antalya. Hope this helps Denny
