Hello All,
Last year my family and I went on a round trip Alaskan cruise on HAL out of Vancouver. That particular cruise, on the way to Juneau, "pulls over" and you can hop onto a small boat and take excursion into Tracy Arm and see Sawyer glacier up close (note: the ship, meanwhile, sails on to Juneau). We did this, loved it and I would definitely recommend it.
This year, my wife's family (we are not going) is also doing an Alaskan cruise, but they are headed out of Seattle and will be on Celebrity. For that cruise, I see they are headed INTO Endicott arm as this is
