I would seriously consider disconnecting and encouraging them to engage with each of you and the world around them. Our kids had fanny packs or drawstring bags that we filled before the trip. It had small pad of paper, retractable pen, cards (while waiting for food or sitting in a very long, non moving line) small hand held toy (dino, princess figurine, army man, car, etc) one of their favorite things was a small disney trivia car game we found, also searching for hidden mickeys. Some of our favorite memories have been from standing in line together...simply laughing and talking. Now that our kids are growing up..glad we had those times! Have a great time with your kids!
