Not all wedding receptions need to be serious or completely formal, which is why you may wish to think about reception entertainment ideas that channel everyone's inner child. For example, you can set up video games, a ping-pong table or even have a popcorn machine that all of your guests can enjoy. You can even take this a step further by creating a temporary arcade for those young at heart.
Another unique idea that very few wedding receptions incorporate is to add a petting zoo during cocktail hour. You can play it safe with cute and fluffy animals, but if you want to get cool factor points from your guests, consider giving them a chance to get close up with a falcon or a tortoise.
