Prior to Embarkation - Stayed one night in Anchorage. Not a great town, very expensive and hotel left much to be desired. Train trip to Whittier from Anchorage was a beautiful trip and well worth the cost ($60) which was less expensive than the bus transfers offered by Carnival.
Embarkation - very small terminal, but the easiest embarkation I have ever experienced.
Cabin - The cabin was located on the rear of the ship. Plenty of room and provided for a great 180 degree view, but was quite wet at times as there was no overhang and the weather in Alaska is not always the best. In spite of wet chairs, I would still do it again.
Plenty of space for two people. Private balcony was great, but no overhang since it was on the back of the ship. Balconies on the sides have a "ceiling", but the views cannot compare to what we had.
