I'm looking at Alaska; Inside Passage, June 2023. The cabin classes vary as such, Classic Veranda, Deck 5, $8890. Superior Veranda, Deck 8 & 7, $9090. Deluxe Veranda, Deck 7 & 6, $9390. So the price goes up as the deck goes up? The description and photos/layout of all of these rooms is exactly the same. Same square footage, amenities, etc. Do you pay more to be on a higher deck? What is the difference between the cabin classes? Any info is helpful. I have only been on Tauck river cruises. Thanks.
