Go on a cruise without blowing through a week of vacation time.
Your family can take a one-night Princess Cruises Pacific Coastal voyage from Seattle to Vancouver, B.C.
(You'll most likely find this type of itinerary during the Alaska cruising season, roughly May through October.)
Spend the evening enjoying the ship’s family-friendly entertainment, and wake up in Vancouver. Then stroll Granville Island and explore downtown before hopping on a short flight back to Seattle. For a more scenic ride home, take Amtrak’s Cascades train.
