don't count on it. I had a note in a recent reservation that my wife will be checking earlier than me as I was flying into town t-con that day. Turned out after some MX delays I arrived at 11 p.m. to find my wife waiting in the lobby because they refused to give her a room key. Same address, same last name, note added to reservation ... the monkeys at check-in didn't care. Needless to say I won't be going back to this property, but having a note added to the reservation may not yield anything.
