We did this cruise & land tour May 2002. Totally unprepared for extremes of weather. On board my fur hat had an outing everyday. There was still a lot of snow & ice on land tour & my walking boots came into their own. Further we got into Alaska hotter it got, wished I had taken couple of pairs shorts. We were on Star Princess & had two formal eves, apart from that smart casual what you would wear to a very nice restaurant. Totally agree have your dressy evening attire in seperate case, so after cruise no need to unpack. If the helicopter trip to glacier still an option, definately book it. Lastly have a wonderful time.
Along with most lines 'semi formal' i.e. jacket required has been dropped, formal & smart casual are the two main dress codes.......Wilba.
We went on a landtour/cruise last year with Princess You are going to have a realy wonderful time. Pack clothes for the landtour in a seoerate case to your cruise, The coach driver then only needs to take your coach holiday clothes on & off the coach. You will need a warm jacket & layers of clothes (so you can put on if cold or take off if warm) But you should get some good warm days in June. For the cruise we had 2 Formal nights the rest were smart casual (no jackets) Have a lovely time.
HI when ar eyou going as we have booked to go on 21st june but we are doing rockies land tour first, agree with the other answers smart is always expected in dining rooms you dont have to wear a jacket. hope you have a good time, .
