I brought an umbrella stroller when mine was 5. It was really useful day one bc camp isn't open until 10 pm. We pushed him around and he fell asleep so we enjoyed karaoke while he snoozed. I also pack individual snacks (pb crackers, gold fish etc) and take them off at stops for him to munch. He wasn't big on the dinners and eating late so we ordered him fries and chocolate milk and let him eat while we got ready so he wasn't starving. I also grab extra milks from breakfast or room service and store them in the fridge for later.
