There are two possible explanations:
(1) unlike anytime in the past history of BWV refurbs, during which there was never a period where all boardwalk view rooms were closed, and that includes times when the refurbs included doing things to balconies and outside walls of the boardwalk view room area (they only did such outside refurb in sections, taking out only a portion of the boardwalk view rooms at a time), there has, in fact, been a determination made to close all boardwalk view rooms, including even the 1BRs which are around the corner in the courtyard area next to pool/garden view studios, for some kind of outside refurb.
(2) there is a system glitch. That is supported by the fact that boardwalk view 1BRs have never previously filled at 11-months out for any time during mid-Sep. In fact, they have never even filled by 9 months out for that time of year. It is also supported by two observations. On Oct 8, 2022, the system showed that at least 1BRs were open for Sep 8, 2023. But despite that, Sep 9 through 14 were shown as fully booked and available only via wait list, That should not happen -- the rooms that were still open on Oct 8, 2022 for Sep 8, 2023, could not be reserved at that time for any dates from Sep 9 to 14th because it would have been impossible to fill those rooms for Sep 9 and after unless Sep 8 was also booked full. Also, as I saw this morning (Oct 10, 2022) at 6:45 a.m. eastern, all boardwalk view rooms were shown as being fully booked and subject to waitlist for all nights from Sep 10 through Sep 16 (with a Sep 17 check-out date). That is an impossibility absent a system problem because, under the 8 a.m. and 7 night booking rules, the night of Sep 16, 2023, could not possibly be booked by anyone before 8 a.m. eastern, Oct 10, 2022, i.e., before 8 a.m. the 7-night cut-off for all actual reservations was still the night of Sep 15.
