The plans get more complicated with children. For those 3-5, then can carry something. Let them carry some toys. Put toys in a small bag, for in case, and let them stay there. Make that bag, the special place for each of them to keep the favorite toys. If you kids are carrying their entertainment, then they are helping big time. If it comes time to bug, then make it part of an adventure. It worked well for the character in "Life if Beautiful." Don't forget also, an empty box is a great toy. Kids have imagination, esp. when younger. Age stifles imagination.
