Like you would love to do the Alaskan tour but my colleague advises thus whales begin their Northbound migration to Alaska in February with the the cows and calves beginning around April and continue their trek through May. If you visit Alaska between June and early September, you may see Humpback and Minke Whales, Orcas, Pacific White-Sided Dolphins, Dall's and Harbour Porpoises. Between June and July, you have your best chance of seeing bubble-netting Humpbacks. So the choice is yours others may offer more info on this subject ... Bill.
We went to alaska with celebrity cruises last september, before the cruise went on the rocky mountaineer train from banff to vancouver which takes two days really worth doing the seven day cruise we stopped at ketchikan,juneau this is where you can go on a trip to see the whales highly recommended their was so many whales we did not know where to look first. after we left the ship we extended our holiday by going to niagara falls.If you go I hope you enjoy it as much as we did. If you want any more info leave a note.
