My fiance and I are thinking of having a pre-wedding reception that would be more of a sendoff/"we give you our blessing" party and then having our ceremony alone on the beach while on our honeymoon.  
I can't find any advice on this.  I feel this would still be appropriate, but how much "wedding" stuff do we do?  Do we treat it exactly like a normal reception? Do I wear a wedding dress?  Do we have a cake, dance, etc, etc.  Any insight on the idea would be greatly appreciated.
