Rainy days:Brassy Apple: DIY laser maze kids activity using crepe paper! You would be surprised how easily kids get in awe when u create a unique fun game at home for them.plus this saves you all the dollars you would be spending at the arcade.
S'mores bar - roast your own s'mores. What an awesome wedding reception idea! Would be so much fun for kids- although wouldn't it be more fun (if you have a small wedding) to have a Campfire outside and roast s'mores
