I've convinced my DS (8) that he must dress up on formal and semi-formal nights, but what about the more casual nights in the dining rooms? Is it ok for kids to wear shorts and t-shirts or do they need to be a more dressy, like dockers and polos? He really hates dressing up and lives in jeans and t's and I want him to be comfortable, it's his vacation too. What do your kids generally wear or have you seen in the dining rooms? Thanks for your help!
