I note (finally bothering to read the itinerary a month before the cruise) that the dress code for the Mariner Alaska cruises is shown as Country Club Casual (hooray!!) for every night except the second one, which is Informal (boo!!). That appears to mean that we have to bring a jacket for one evening, right? A related question is whether Signatures (which is always at least Informal on normal cruises) will be Informal on all evenings on the Alaska cruises, even though the ship is CCC six nights out of seven. Any clarification from recent Alaska cruisers will be appreciated, as I try to find a blazer to go with my muck-lucks. Cheers, Fred
