We've stayed at Kidani and Beach Club villas. The biggest difference to me is that there's a sitting area - I know you said you already know about the configuration, but it's the use of the room that different. We are able to sit somewhere other than the bed, can eat breakfast somewhere other than the bed or the floor, and then can clean up somewhere other than the small bathroom sink. That makes the trip more enjoyable to me, since everything feels a bit less chaotic and messy.
