I sailed to Alaska with Princess,can;t say the entertainment was brilliant but plenty opportunity for dancing and the food was first class.Book a balcony cabin if you can on the side facing shore because the scenery is out of this world.
Thank you for your reply infact we were thinking of Princess but tell pls. how would you know which side will be facing shores???
If you are going up the inside passage towards glacier bay you want to be on the right hand side.you won;t be dissapointed with princess diamond &sapphire are big beautiful ships and in my opinion superior to costa & ncl.we went in september and the weather was balmy but not to cold.you will see whales sea eagles and possibly bears if you like that .hope this helps have a great trip .
If you do Costa then I would suggest NCL or Carnival.
Thank you for your remark may I kindly ask why comapring NCL or Carnival in what ways.
