Probably not for two reasons. First, I would never get where I needed to be because I would get distracted. Second, you probably couldn't get up the stairs through all the people playing on them. It would become a playground for little kids.
While I can't hear it, I am presuming it makes noises when you step on each stair. I think that't be fun - but as the only time I use an escalator is in this one shop, I'd probably use the stairs anyway.
