Just got the seemingly "official" ride description release in my Disney Rewards news letter:
"Boo's on the loose in Monstropolis, and its up to Mike and Sulley to get her home! Experience a whole new level of laughter.
The desciption goes on to say that this ride is designed for families with children under 10 years of age.
Join Sulley, Mike and Boo as they try to avoid Slithery Randall Boggs and an Army of yelow suited Child Detection Agents. You'll race through Monstropolis and into the halls of Monsters, Inc to Boo's bedroom."
