I absolutely concur with the latter half of that statement (bolding was mine). If the hotel was unresponsive in addressing the problem, I would fully expect Starwood to act on the OP's behalf to "extract compliance" from the hotel, and if the hotel itself did not own up to the problem, then I would further expect Starwood themselves to take some sort of action themselves.

That being said, in this case, the hotel did make an effort to address the problem. For that matter, SPG did as well, above and beyond what was required. The problem is that the OP has not specified what it is they're looking for in terms of either compensation or other renumeration -- they're just expecting a better offer. If the OP had said "the hotel further needs to reimburse me for the time it takes me to put my work information back together from other sources", and the hotel refused, then I'd expect the OP to discuss that with Starwood's Hotel Customer Service, and have them help negotiate a reasonable arrangement. Until the OP specifies what they're looking for, however, I don't think SPG or Starwood have any responsibilities in this matter.
