On our Alaskan cruise earlier this month, the Mariner didn't even see the Sawyer glaciers. We cruised into Tracey Arm and enjoyed a 360* turn in one part of the arm and saw lots of icebergs. This catamaran excursion should get you up close with both glaciers.
If you get up early that morning, be sure to be up in the Observation Lounge. That was the morning we were entertained by the pod of humpback whales. Maybe they will still be in the area. That was one wonderful show for us.
