We just returned. We were a CAT 9, so it may be different, but there was no radio. We had the TV which had a sleep timer on it - which we used to fall asleep to and used it as an alarm clock in the morning as a back up to the wake up Mickey calls. There are some channels that tell you the ships location, and where all the stores, restaurants are. They just have music on in the background while the facts/maps flash on the tv, so maybe you can put the tv on those channels and set the timer?
