I have 3:
The Rebak Island Resort - A Taj Hotel is a great family resort with morning nature walks, kayaks, bikes, a great pool and wonderful service. Great value too.
If you like a little bit fancier, The Danna Langkawi is gorgeous, biggest pool on the island, plus has a great kids club.
If you want to be a bit closer to nature and your family likes cats and dogs, go to Bon Ton or Temple Tree resorts (sister resorts, right next door to each other). You stay in antique buildings, restored with modern amenities added. And because the resorts are affiliated with a nearby animal rehabilitation centre, you can walk dogs or pet the sleepy cats that hang around the resorts. No beach, but three pools to choose from. about 6 years ago
