The more I think about it, the more I don't like this episode. Nothing fits. The hotel idea makes no sense. Why would they keep the people they've sent back in time unless they were going to continuously send them back in time and feed off that energy? More importantly, why can't the Doctor ever see them again but River obviously can (since she gave Amy the manuscript to publish)? It's, quite frankly, contrived and beneath Moffat's ability.
