Yes Helijet is great. We arrived off a Princess cruise from Alaska and as it was a Saturday, it was off peak fares. The scenery was fantastic and just three passengers! I booked online too. You must be a Canadian.
I've done the same cruise with Princess, fantastic. 4 of us did a helicopter trip over Mt Robson on a Rockies tour the week before the cruise. I expected it to be a Chinook, but it was a little glass bubble. It wasn't part of the package though and arranged as a one off through the courier. We were OK with that but wouldn't have done it with a local cab driver. Can't remember how much it was.
