There's the current map of Universal/Stan Thomas land ownership in Orlando. Universal's land ownership for the south resort is now over 1300 acres. H/T to
@Happytycho for checking the land records and finding the specific parcels Universal got.
I included the Kirkman extension on this map because that right-of-way was already granted on that specific route, so Universal will have to deal with that as it is.
The Mandarin extension (the one cutting across large parts of the property from Universal Blvd. to Sand Lake) is not included because I assume Universal will move that path before actually granting right-of-way/building it, to maximize Universal's land usage.
