Could do this in each of the kids' rooms.Kind of like this idea for the wall at the end of the upstairs hallway. When the kids are heading to school or out, they'll have a sweet reminder of how much they are loved :)
***this would be outside (maybe on the deck or near a tree). A bucket of water with floating votives.*** Like the idea of guests lighting a floating candle and making a wish for the bride and groom. Placing it in a small pond or boat filled with water.
