People eater is a relative term. It certainly depends on various factors (are we talking a traditional playground or a 'play exhibit', how well attended is the area, how well do they make use of the space, is there seating that encourages parents to stop and hang out for awhile, etc.) But yeah, I'm using the term 'people eater' in the way that people do when they talk about needing additional indoor shows or B list attractions as people eaters. It's certainly not going to be on the scale of an omnimover with a long line, an outdoor show / parade, etc. It would need to be one of many small attractions to help with crowds.
