Pleasure trip to the moon! Who would not want that? Who would want to fly in the sky as a bird? It would be great to simply go to the moon and sit quietly and gaze at the stars. It would be awesome to play with Krypto among the asteroids. This pleasure trip is not trivial imo.
Granted after Crisis he could not take Krypto for a walk but even then he experiences the world on a different level.
