Bridal Party Dance & Last Dance Song?

My Fiance' and I are trying to decide on a bridal party dance song and the last dance song. We want to use either "Bless The Broken Road" by Rascal Flatts OR "Making Memories Of Us" by Keith Urban. Which ever song we don't use for the bridal party dance we are going to use for the last dance and vice versa....I hope that makes sense. But we can't figure out which song would make a better bridal party dance and which song would make a better last dance. Any suggestions? We know for sure those are the 2 songs we want, so changing them is NOT an option. Thanks =)
