Almost all wedding gifts are stuff. And sometimes that's what they end up being, just stuff in the house of the newlyweds.
You don't want your gift becoming just another object, but something the couple uses.
One way to do this is to give your favorite new couple an experience.
Yes, you read that right! An experience.
If you give them an experience, they will keep that memory forever, and possibly love it so much that they do it again!
