"In to" and "into" provide people like us endless fun. It is sometimes impossible to tell which we should write. They sound the same, and the meanings overlap quite a bit. Neither belongs in your phrase, though, so we are spared this time.
My initial reaction was also that a simple "to" would be best. But looking at it from the writer's viewpoint, I wondered which of the two, "in to" and "into", could be used. My intuition says "in to" might be OK, since you might say to your child, "take those in with you". OTOH, I could not find a definitive rule.
