They do the same with the monorail and that has existed fine for quite a while. The restaurants on the monorail loop *want* foot traffic. This forum and the internet can't say enough about going to the restaurants on the monorail loop. You may want a hotel devoid of guests, the hotel doesn't. Besides the Crescent Lake resorts are full of crowds worse than mere vacationers... they're overrun by conventioneers!
Naming the resorts that are already on Crescent Lake and then adding in the new resorts that will have Gondola access to the IG overstates the case of extra traffic. The IG already handles the traffic from the Crescent Lake resorts. It will add on CBR, Pop, and AoA... at least just those people who would have bussed to the front gate of Epcot. That's not really a significant extra number, especially considering that when the Gondola opens, the people choosing those resorts will have their eyes on DHS and SWL.
Monorail resorts have paid premium prices with folks using the monorail to go to their restaurants. You're not paying extra for reduced crowds. You're paying extra for being walking distance to two gates.
They could, but WDW has no reason to. They want people to go to the BoardWalk and the other Crescent Lake restaurants. They regularly advertise BoardWalk to all guests.
1. The gondolas can dispatch 200 people every six minutes... so, don't worry about crowds. Besides, the line-up will be for the people at the far-away resorts. The Crescent Lake people would just walk past them.
2. Jim Hill on Disney Dish is just wrong about WDW having no plans for the IG crowds. He's been wrong about a lot of things.
There is deceptively plenty of space. Big swath between the tapstiles and canal. A lot of area leading to the bridge. A lot of area left over around the station. And a lot of area on the walk way on the opposite side of the ferries.
There will be more capacity added for tapstiles. (Note the spelling of 'tapstile' as a variant of 'tunrstile'
)
