Yes, Little Lake Bryan was developed by a subsidiary of the Walt Disney Company on Disney property.
See "
Disney charts new land deals," by Donna Young, Staff Writer, Orlando Business Journal, June 5, 1998 print edition.
Here's a quote from the article:
<blockquote>
ORLANDO -- The Walt Disney Co. and its subsidiary, The Celebration Co., are quietly cutting deals to build hundreds of new hotel rooms, thousands of square feet of new office space and, for the first time, seniors housing in the town of Celebration.
Among yet-to-be-announced projects outlined in confidential company documents:
- Hotel giant Marriott and Orlando-based CNL, a real estate investment trust, have agreed to develop 1,100 hotel rooms at Little Lake Bryan on Disney-owned land in southwest Orange County.
The parcel, which fronts Interstate 4 and State Road 535, will include 1,100 hotel rooms under the name of Marriott subsidiaries Fairfield Inn, Fairfield Suites and Courtyard, as well as three free-standing restaurants.
</blockquote>
Aside from the fact that Marriott renamed its Fairfield Suites brand to Springhill Suites before the hotel opened, that's exactly what happened.
In 2000, Marriott sold the hotels to Orlando-based CNL Hospitality Corp, but continues to operate them under three Marriott brands.
In 2001, Disney sold the CrossRoads of Lake Buena Vista retail center. For some reason, I thought that Disney also sold Little Lake Bryan around that time — but after a few Google searches, I can't find any news about this. So I don't know whether or not Little Lake Bryan is part of Disney.
I wouldn't rely on roadmaps tp show exact, current property lines. Maps, such as the
AAA Orlando South map, show WDW boundaries that haven't changed in years. The maps are updated as new roads are built, but not as parcels of land are added to or removed from WDW.
