I remember reading that Retlaw sold the Disneyland Monorail, Disneyland Railroad, Walt Disney's Enchanted Tiki Room and various Disneyland enterprises back to the Walt Disney Productions in the early 1980's, just prior to Eisner coming on board. And according to a quick check on Wikipedia, Retlaw did in fact do that in 1982, although Wikipedia has been known to be off on dates a bit.
Retlaw continued to exist to the turn of the 21st century, owning several California TV stations, farmland and a charter jet service. It devolved back into the Walt Disney Family Foundation a few years ago, just prior to the Walt Disney Family Museum opening in San Francisco's Presidio.
And anyone who claims to be a Walt Disney fan simply MUST visit the Walt Disney Family Museum. It's just stunning, and highly informative. There's info on Retlaw and its role at Disneyland and beyond at the museum, by the way. There is practically no information about Walt Disney World there, however. Only stuff that Walt actually created and worked on.
