I have been on about 10 cruises all with major lines (mostly disney with our kids). My wife and I are looking to take our first cruise to Alaska, and our first couples cruise without kids. We think we want a luxury cruise, but Im having a hard time discerning which would be best. I understand there are so many variables, and at this moment I am leaning towards a Seabourn cruise, but am open to any suggestions for a fantastic luxury cruise with late july early august window. Many thanks in advance to any input.
