How would the Watsons trip been different if they had followed mommas plan?

If the Watsons had followed Momma's plan to leave Grandma Sands at home and visit Disneyland instead of visiting her in Birmingham, they would have avoided the tragic church bombing that took Grandma Sands' life. Their trip would have been filled with joyful experiences at Disneyland instead of being overshadowed by the heartbreaking events in Birmingham.
