Bringing a First-Timer — Ideas?

We’ve been to WDW a few times, but it’s been awhile (2017). This July we’re returning, and bringing our exchange daughter from Denmark. She’s never been to WDW and likely this will be her only trip there. Any particular advice or ideas to make this once-in-a-lifetime trip extra special for her?
