There was small children drew into the concept art... and discussions about entertainment for all ages.
Agreed. This will indeed be family friendly because it's Bob Chapek's mantra: timeless, uniquely Disney, and family friendly.
Every deluxe resort has play areas for small children. Cruise ships have events for children to participate in. I would bet there would be an arcade with SW games, just like on the cruise ship. Wouldn't be surprised if families with children make an excursion to DHS for their own Jedi Academy. Older children will readily follow along with parents on whatever light or heavy LARPing there may be. In then end, they'll probably wind up leading their parents around. SW dance party? Sure.
Would this bother some adult LARPing purists? Yep. But they're the ones that will have get over it. Hang out in the bar (which may be the one place children aren't allowed, along with an adult pool/whirlpool) and have an hour long discussion of galactic politics with the CMs and other LARPers.
