IMHO the first image is by the far the strongest, the colour blue yellow blue sandwich works so well, still has rich black, its got reflections and has interest in it's unusual pool and palm trees presentation.
The only two things I would do, is to clone away all the lights from all the buildings on the hills in the distance and also clone out the black blob in the sea just to the right of the palm trees, a quick two minute edit.
Then get printed large and hung on the wall and or alternatively sold for very large fee to some travel company for their exotic holiday brochures, it's certainly good enough.
