We're flying into Anchorage and taking the train to Seward to board Mariner. We won't get to Seward until 4pm or so as I understand it. Is there a handy place there to buy diapers and other baby essentials we don't want to schlep from Missouri, or should we get them in Anchorage prior to getting on the train? We have RSSC transfers, so we shouldn't have to cope with luggage (I hope! tell me if I'm wrong...)

Also - we're looking at Captain Larry in Juneau and were thinking the sunset cruise might be nice. I've heard great things about his service, just wondering if anyone had experience with an evening excursion.

Thanks!
