Here's about the best example I can find John. Same subject (Bellagio), same lighting (all artifical), darker photo.

It keeps the detail visible in the really light bit at the top of the hotel (you can still read Bellagio) BUT this is at the expense of the hotel appearing darker and also losing some of the lovely reflections in the water. My water is quite dark and boring by comparison to yours.

It's a real compromise with no real right and wrong answers. The best tip is to try a whole bunch of photos and see which works best.
