Seems like it may have some use, until alternative propulsion technologies are developed that can cover the vast distances of space in reasonable times then such a technique opens up the possibility of freezing explorational crews/colony seeds and throwing them out to other stars - and being able to defrost more than corpses.

Also, props to Disney, he had faith this day would come.

I think living ships would be more sensible. Have the crew alive, living on board the ship, dying on board the ship when they got old, etc. Being put into stasis seems terribly boring, not unlike letting your kids take some sleep-inducing motion sickness pills before a long trip so they sleep the whole time, giving parents a much needed quiet drive. It is not the kids that get anything out of it, it's the parents.

Unfortunately, "living ships" don't do too well for misisons that might take hundreds or even thousands of years. Much more resources consumed, and thirty generations later will they even know why they're there, let alone want to be there.

What the kids get out of it is when they wake up after the quiet drive is doing something never been done before.
