Well, the Crayola Experience is an actual attraction (with a sizable gift shop). You pay to get in and do highly interactive stuff. I think if it were to come to Disney Springs, something pretty big would either need to move out or it would need to be a new addition.
It would probably be a good fit for Disney Springs but the crowd, I think, would be very different from what they're pulling in today at Florida Mall.
The one at Florida Mall is due (IMO) for a refresh. I wouldn't say I'd be unhappy with it moving to Disney Springs if the price to get in didn't jump.
Instead of choosing between it and M&M World, I'd say the Crayola Experience might have been a better fit than the NBA Experience - although a lot less splashy of a thing to announce (and at the same time, probably a much cheaper overall investment).
