I don't mind this, but it seems like a waste of the hotel's time. It seems like would take a fair effort combing through the returns of a Google search to find any information that would be useful for hotel staff. I think that adjusting service in response to information that is publicly available, but not specifically provided to the hotel by the guest, is a pointless effort at best and risky for the hotel at worst.

I like the idea of the chain keeping a file on guests. They should collect data on customers who complain incessantly. Shame on them for letting the customer see this information, though!
