We're just back from the 5/22/17 sailing.
MDR's were not chilly to me. Not super warm, but I was comfortable. I did bring a sweater/light jacket with me, just in case.
I think Captain Robert?
There was some Alaska specific merchandise, but I'm not a big shopper in that way, so ... pretty sure t-shirts, jackets, there was Alaska cruise scrapbook paper, the Mickey and Minnie small plush with their Alaska outfits.
Cruise was awesome.
We did the Glacier Explorer, which I have mixed feelings about whether or not it was worth the extra expense, since the ship got pretty close (not as close as the smaller excursion boat). In Skagway, we did the train/snowshoe adventure, which won't be offered the rest of the season. It was so much fun, but the snow is melting as they have had some warm days. In Juneau, we did whale watching (booked independently through Harv and Marv) and saw quite a few orcas and humpbacks. In Ketchikan, we just ran/hiked/walked around on our own and went to an early dinner in town.
