I have zero inside info on this, but I'm going to speculate that Walt Disney World's physical Club 33s are going to be more like the corporate VIP lounges that exist around property with a bit more emphasis on light food and adult beverages. Places where Members will be able to duck into and relax, have some drinks and perhaps a limited lounge light food menu, away from the masses. Very similar to Club 33's "1901" extension at the California Adventure Park. I don't think they're going to build a full blown restaurant at any of them like Disneyland in California has. I could be wrong of course.
Club 33 in California was for most of it's life...simply a place...a private restaurant. Today, Club 33 in California is more of a complete exclusive service program that includes VIP tours, special viewing areas, special events, handfulls of Fastpasses, 1901 Lounge & Bar, valet parking, hotel upgrades, etc, etc...and the physical original Club 33 restaurant which is now just a part of that whole membership "package" if-you-will. Today, Club 33 no longer refers to a place (in fact, its entrance and address is no longer even located at 33 Royal Street)...it refers to a whole membership program.
In a nutshell, in Florida I think it's going to be some VIP lounges plus some of the VIP access and services that are part of the traditions and benefits of their California counterpart. A way for you, your family, guests and clients to enjoy some very special and exclusive experiences when visiting, many in an uncrowed unmatched setting.
