Early on when BWV was announced, there was to be a "DVC Member's Only" area for viewing the EPCOT fireworks/Illuminations. It was to be called "The Attic".
When sales began, this area was separated from the resort itself and no longer a DVC perk. "The Attic" is there (near the JellyRolls area but not on the ground level), but is an area reserved for private events. It is a beautiful facility, but has never been used for any DVC events that I am aware of.
TOTWL lounge was announced in similar fashion and, to date, been kept as a DVC Member only facility - but is not truly part of the BLT resort (paid for and supported by BLT owner's dues). It could become a private (or public) facility at any time.
