Hi!
While I am not a photographer, I am a bride that was recently married at Aventura Spa Palace (Dec 07). Here is a link from my photos from our wedding:

As you can see the sun did set behind the resort, not over the ocean. However the colors in the sky were beautiful. Keeping in mind the sun sets earlier in December than June, we had our ceremony at 2:30 followed by cocktail hour from 3-4 and did pictures between 4-5 when the sun was setting.
I hope this helps.....
