Don't listen to what everyone else is saying...They are not gonna stop you from eating if you are not following "dress code". Sure, adults who wear jeans will look out of place, but as far as kids go, let them wear whatever you feel will be best. Don't go crazy bringing so many different clothes for them to change in...shorts will do just fine. On my cruise (also Miracle 6/12) people were wearing all kinds of stuff...some jeans and some tuxedos. They didnt stop anyone.
