best beaches

I was discussing a beach wedding with my fiance, and I was wondering what beaches would be best for our wedding. We want somewhere pretty secluded, because we dont want people all over the place at our wedding. Plus, we would like a place that has an ideal area for a reception nearby. I know my sister had her wedding on a beach in Maui, that was right behind a fancy hotel, and we had the reception on this little back patio type thing. This is kinda what we’re looking for. Does anybody have know of any places or hotels that would be ideal?
