The Fjord was beautiful but not worth the price that cruise charges. You are better off booking this excursion one you disembark at the visitors center. We saved about $80 by booking there instead of the ship.
Would definitely recommend this to everyone. The tour was $79 and they will take you into the Yukon to Carcross. You will get to visit Emerald Lake. Beautiful place. It does get hot here if the sun is out so you might want to wear light clothing. They are very flexible and will accommodate your requests to stop at certain lookouts.
