IMHO, I think unblocking AP's would really be a mess because it is terribly unfair to those who upgraded. Unblocking CM's I would imagine is pretty easy, doesn't cost them anything, and not a PR disaster.
Full rack rate rooms are just sitting there not getting booked. That is a lot of revenue they are losing. People who stay onsite don't leave ... therefore generating more food/drink sales too. Bring back discounted rooms or a package deal!
Oh man would I love some discounted rooms... I doubt it’ll happen over Halloween season, but I would LOVE to knock some off my $2800 standard DLH room T^T
