It’s got a decent message it’s trying to get across: don’t get so wrapped up in the future that you miss the present.  But I had a hard time getting especially excited about either the plot or the illustrations — both seem a bit under-developed.  Stewart is a rather ugly little monster who is having a hard time waiting for his first camping trip, and he terrorizes his parents trying to speed up time, until he talks things over with a classmate who is dreading vacation because she’ll miss school; then they both agree to enjoy the present, and before he knew it he was camping.
