Alaska Cruise any recommendations? 5 D+lenses to bring

Greetings,

The search feature is down and I would like a recommendation for lenses to bring for an Alaska cruise,

Currently shooting with a 5D, 17-40 f4, 24-105 f4IS, 70-200 f4IS, 100 2.8 Macro. 1.4x telextender. Do I need longer?

Any suggestions for trip intenerary ie. Glacier NP, Inside Passage, Hubbard Glacier, Tracy Arm, etc. for a first time cruiser.

Thinking of flying into Vancouver, BC for 7 day cruise northward.

Recommended cruise lines?

Best weather month?

Optional shore excursions? Denali?

Thanks.
