For the generations & families that visit now, yes. The franchise is bigger than ever, and people know Disney for their movies, the theme parks are an added bonus. If they have the material, why not use it? I guess you could even say original rides like HM and POTC are now IP, due to the movies being released using inspo from them. Young kids don't want a globe in the middle of the lake or old, outdated movie sets on a ride. They want (begrudgingly) Elsa and Anna, they want Mickey Mouse and they want characters. If Disney own it, I see no reason to not use it to their advantage, especially if it's updates to attractions that have had their time.
