first off, i grew up at the Jersey Shore... I know the area and the boardwalks... and secondly, they already did try to recreate a 1940s era boardwalk environment which is the resort itself... I am not talking about a present day boardwalk...lol but the same sort of vision that the resort was based on... This would not literally be Wildwood boardwalk dropped into WDW.... any more than the current hotel is not literally Atlantic City... There would be no hoards of unsupervised teens...no hoodlums and organized crime... It is a restaurant allowing people to eat after the parks close.....
There are 6 resorts directly in the Crescent Lake area... that is 4,868 guest accommodations including hotel rooms and villas... I think that is enough people to serve not including the guests that would be traveling through on the Skyliner during operating hours...from the Riviera , CBR and AOA resorts...which is an additional 5,836 rooms... The restaurant could theoretically be serving 10,804 guest rooms.
By late night I am thinking of the hours between 9pm and midnight... There are tons of people that stay for the fioreworks and are not ready to go directly to bed...that would appreciate a place to get a little food or drinks... It has happened many times to us that we get caught up in doing too much, stay for the fireworks and then realize we missed dinner and there is no place to get anything to eat without getting the car and driving off property... There is a reason the lines for the McDonalds near the All Star Resorts and at The Crossroads was always ridiculous late night...
There is a need... And the Boardwalk/ Crescent Lake is one area that would address the largest amount of resort guests from one location...
