DUET VIDEO HELP!

Okay so duet allows two songs for the wedding part of the video. one for what they call formal- which is the part when we take pics with each other n the family & bridal party and then recap- the moments throughout the wedding. initially i was going to pick a party song for the recap then I realized i cant bec there will be clips of the ceremony too and i want a slow song for that!

I contacted them to ask their opinion but havnt heard back yet. does anyone have their video yet and can share what they did??
