Do hotels have too much data to handle these days?

This evening, I am participating in a interesting debate with hoteliers (mainly revenue managers, finance and sales directors) where we would discuss this question:
"Given the ever increasing accessibility and complexity of Benchmarking Data and public on-line Customer Reviews – do you believes that Hotels cannot realistically take full advantage of all the information available?"
I would be very interested to hear your view as a hotelier whether you are independent or part of a hotel group. I believe answers will be different depending on the status of your hotel and also your responsibility in the organisation.
