3. Alaskan Adventure - Princess Cruises' Inside Passage Discovery

Princess Cruises' 7-night Voyage of the Glaciers itinerary represents one of the most spectacular cruise deals available, with interior cabins starting at $95 per night during select sailing dates in May and September. This Inside Passage journey aboard ships like the Ruby Princess or Emerald Princess offers front-row seats to some of nature's most dramatic performances, including calving glaciers, breaching whales, and soaring eagles against a backdrop of snow-capped mountains. The itinerary typically includes Juneau, Alaska's capital city accessible only by sea or air, where passengers can experience everything from helicopter glacier tours to salmon fishing expeditions. Ketchikan, known as the salmon capital of the world, offers rich Native American culture and the famous Creek Street historic district. The highlight for many passengers is Glacier Bay National Park, where the ship slowly navigates among towering glaciers while park rangers provide educational commentary about the ecosystem and geological formations. Princess Cruises' partnership with the National Park Service ensures authentic experiences that go beyond typical tourist attractions. The shoulder season timing of these deals means fewer crowds at popular attractions like the Mount Roberts Tramway in Juneau, while still offering excellent wildlife viewing opportunities as animals prepare for seasonal migrations.
