It's a BWI tax. It's a deluxe resort charging rack rate of $1,000 per night. BWI and the Boardwalk isn't for the poors.
Been a long long time since Disney once advertised the boardwalk as a destination for all guests. Seems they're happy with just the deluxe guests using their amenities.
I like the boardwalk area, thought to be honest when we choose to stay in the Epcot area, we normally go Swan and Dolphin as I like the pool, and the restaurants and i think you get the same experience and location for a reduced price (or free if your using Marriot points.)
But that aside, I just don't see the want/infrastructure available to try and focus on the boardwalk being a destination/entertainment venue for all WDW guest. If you're a hotel quest, at a deluxe resort, do you really want your resort area turned into just another entertainment center. If everyone can use the area, why are you paying deluxe prices for it.
Second, what type of destination area do you want the boardwalk to be? Food...shopping...you already have Disney Springs for that purpose. Entertainment? You have that in the parks, and Springs to a degree.
An evening/later night location? Again Disney Springs is already there. I will admit I could see some fun possibilities subjectively to having the dance hall open more, some areas to enjoy drinks, music, ect. and its a fun place you can watch the Epcott fireworks. But I don't know if they would set up for their own success. Getting any significant amount of people into/out of the area at night is going to be problematic. And once again you're turning an area with guests paying deluxe rates to sleep into a nighttime feature location, i am not sure many guests are going to want it.
