Disney's been doing awesome work with "Living Characters", like a Mickey that moves his mouth or a BB-8 that can roll around. But for various reasons, they never tend to make it into regular usage.
If you have a few hours over Christmas break and want to watch a 4 hour YouTube video (I promise if you're on HN on a Sunday, you'll be delighted by it), I highly highly recommend this video:

Nothing about all that tech makes me think Olaf could withstand a hug from an excited kid.
Disney does a ton of R&D that doesn't directly make it into the parks, such as smokeless fireworks (they donated the patent for this) and their holotile floor (basically an endless VR room you can walk around). I imagine they don't know the practicality at the start, like any good R&D.
There are a few older shorter videos in the half hour range, I highly recommend checking them out if you find some quiet time! (It's awfully hard for me too in recent times, I haven't gotten around to watch the Living Characters one myself, so I can't give the gist... I'm just glad I got the holidays off to finally catch up!)

She covers everything - the line getting in to the hotel, the size + cost of the rooms in comparison with the same size/cost on a Disney cruise ship, and theories on why the experience was so poor.
Totally get it's difficult to make time with kids, but depending on your kids ages... the video shows a LOT of Disney characters talking and doing things and the videos are colorful, so it could work as something you can listen to and they won't mind having play in the background!
For example, the working WALL-E robot that's made a handful of PR appearances weighs seven hundred pounds. They absolutely can't risk that ever running across some kid's foot.
The Disney wiki has a pretty comprehensive list of usages for the "articulated heads". It's more than I remember it being.

Much like Olaf (and many before him… dinosaurs, talking characters, etc), it was implied he’d wander around the parks. But it tends to happen for a short amount of time, mostly for media, and fade away quickly.
Maybe I’m wrong, but I’ve seen this exact thing happen a dozen times over the past 20+ years. Watch the video I posted if you want to learn more!
We already live in the world where hackers are pwning refrigerators, I can't wait for prompt injection attacks on animatronic cartoon characters.
It's not necessarily AI controlling the communication. Disney has long had 'puppet' characters whose communication is controlled by a human behind the scenes.
He looks nothing like a snowman. Snow doesn't look fuzzy. This project appears to focus more on trying to get it moving around in an animated way than getting the character to look right, at least when viewed from photographs.
The tech is amazing, but they need better sewing...
