I'm only assuming this is what you are talking about. Getting rid of Disneyland Dr. allowing the expansion to easily roll over to the west without the need for bridges or tunnels.
So now there is no need for front drop-off entrances at PPH or GC that are a staple of large hotels because the public can't get there anymore. No drop-offs, no valet. The PPH parking garage is now useless for the same reason. How do hotel guests get to their hotels? Park at Mickey and Friends and walk with their luggage for half a mile? And how do delivery trucks get supplies to the hotels and remaining restaurants in DTD? Do they go through the theme parks? Perhaps they build an access road just north or south of the DLH, but that just adds traffic to Walnut which the city and its residents would be against.
I think the logistics behind this would be greater than simply building two more bridges.
