For what it's worth. I finally was able to cancel yesterday. The hours being cut back at the hotel made it tricky for me to get anyone at the actual property and not a reservations line.
Lady today me anyone booked under the Thubderbird group was canceled out already.
Also she said Bart has secured a new block of rooms at a different property as they were already booked.
Not sure if anyone spoke with Bart but there may be a block of rooms somewhere.
