My fiance and I have chosen Lost in this moment for our wedding song. Is there any advice as to how to dance to this? We know some of the basics of the waltz, swing, fox trot, cha cha, and rumba. I don't know if any of those fit. Any help or ideas would be great!

Which version? If it's Michael Buble's original it's a very, very, slow rumba, and quite challenging to dance to.

It seems like posters who want advice for dancing to a wedding song really pick some tough ones. But that happens at the dance studio as well. I have seen instructors just tell couples to forget the song they picked, or forget worrying about doing a proper dance to it. Seasoned professionals would come up with a routine, quite likely a slow rumba, to this tune, but a wedding couple will have a tough time with it. Oddly enough, the version of this song by Keith Anderson is a little quicker tempo, and it almost gets to a point where you are thinking of a Viennese Waltz to it. But it just doesn't fit that either. I too would suggest trying a few slow rumba sequences and slow turns to see if you could make something look nice and elegant with it. A teaching pro certainly would provide solid advice.
