Both Ralph movies -- using the ballpark equation to figure out the profitability of a movie during its theatrical window -- barely broke even. They did each bring in half a billion, but they were also very expensive to make.
Which is fine for Disney. That meant all the aftermarket (merchandise, DVDs, Cable, Streaming, Broadcast, theme park leverage) is all (mostly) gravy. And considering the billion dollars in ticket sales, they can expect a hefty aftermarket.
Both Ralphs got fairly good reviews from critics and audience (the first doing slightly better).
This puts Ralph in the position of being fine to use in the theme parks if it fits. But, it doesn't mean there's any hair-on-fire running around trying to figure out how to immediately parkify him as there was and is for Frozen or Marvel.
Ralph & Vanellope show up in the special parades, HEA, a 'permanent' M&G spot, and a barely themed kiddie playground. I'm sure they'll show up in this Spring's DHS projection show highlighting Disney animation.
According to insiders Ralph was once considered as a Stitch replacement, but that's off the table. And a Sugar Rush overlay was considered for Speedway, but that's off the table. Ralph seems ready-made for Tomorrowland, especially complementing TRON. But, TL's problems are another story.
