I'd advise agaisn't this right now...I've seen some reports elsewhere that people had issues with the key printing machines, needing to show their ID, etc. While it may look good, there are still many things that could go wrong and then you not show up and get charged for a no show. I'm not sure I'd be ready to run full speed into something that could not work...Seems the Rio still has some issues with check in, etc.
