I would encourage OP to name the property, as we have heard back from OP that the hotel has indeed stepped up recovery efforts and stated that some of the staff is new.
(Well, it looks like it was a new FD agent, and maybe a new manager? since the initial manager was also nonchalant about the issue.
)
Let us know what is the final gesture which you have accepted.
I do give credit to properties who bother to recover from service lapses, so this is a positive.
The good part about sharing the property ID is we can see if there is a consistent pattern in the hotel delivering rooms way past official check-in time, as well as the nonchalant attitude when they fail to deliver the rooms at 3pm.
