That isn't happening, the are no plans to build a new Hotel or do a major Downtown Disney Remodel.
What they want from the city is ways to address parking. So bringing back the Eastern Gateway project, which will allow the Transportation plaza to be moved to Manchester, opening up land next to DCA/Disneyland, to allow park expansion. That is a five year plan, though the Pumbaa parking structure might not be built right away, waiting for the USCIS leases to expire, allowing it to be built in one phase. What Disney needs is the Bridge over Harbor, the new security check and ticket booths (and restrooms), plus the new Transportation Plaza for ART and other shuttle Buses, Public Buses, Uber/Lyft/Taxi area, a drop off area. Basically freeing up as much land as possible on the East End of the park (West side of Harbor). That is worth a lot more than any Hotel or new shopping. (Aka Park revenue and parking revenue is a much better profit maker).
