Alaska Cruise Planning Tips

Cabin Selection

Choose starboard (right side) for northbound sailings to see more coastline and glaciers.

Balcony cabins are worth the splurge for Alaska—glacier viewing from your private space is unforgettable.

Mid-ship location provides the smoothest ride if you cross the Gulf of Alaska.

Excursion Booking

Book early for popular activities (dog sledding, White Pass Railway)
Compare ship vs. independent — Ship excursions guarantee return; independent often cheaper
Consider a helicopter/glacier landing — Bucket-list experience
Don't over-schedule — Scenic cruising (Glacier Bay, Hubbard) happens on the ship

Budget Considerations

Whale watching: $150-200 per person
White Pass Railway: $150-180 per person
Helicopter glacier tour: $300-500 per person
Dog sledding: $400-600 per person
Independent walking tours: Free-$50
