Hands down, Alaska is probably the most stunning place I have ever been. You are surrounded by natural beauty wherever you go. So... :)
Background: Solo traveler, but I was with a group doing a staged marathon throughout the cruise. Previously cruised on Disney twice.
Hotel: I stayed two nights at the Hampton Inn Seattle/Southcenter, and it was fine. Standard Hampton Inn, which is fine with me.
Smaller than what I'm used to on Disney, but it was fine, particularly as I was solo. I'm not sure I'd try putting more than 2 people in the cabin. The balcony metalwork did have some rust issues, even a hole around one of the screws, and the glass was tinted, which made it challenging to see through. Still, it was generally fine.
