Good advice from Tammy and I've always found the Monte Carlo Tower to be fine. Actually, I don't think you could go wrong in any of the towers as they are all located centrally and handy to the convention area/buffett/Splashbar and casino. Nothing to really worry about pre-arrival. They feature self-checkin on termials at the desk but if you can post on Greg's board you can handle the transaction without problem and the nice folks at the desk are fast to respond if you should have a question or such. The Riv always treats us very well so have a good time!
