Superbex & family

My daughter and her partner & 2 girls are coming to Icmeler 4th September can anyone offer tips and hints other than the usual ones?? The swim nappies are an issue at the min as the baby will only just be one and is not allowed a luggage allowance! They are staying at Ekinci Palace, are they near enough launderette, shops, take away, supermarket etc. Thanks in advance to anyone else travelling with a 2year old with a one year old sister
