UnCruise Adventures' 60-guest Wilderness Adventurer is a soft-expedition ship that cruises in Alaska, including the Inside Passage and Glacier Bay National Park. The ship lacks the bells and whistles of larger vessels (there is no pool and just one dining room and lounge) and activities revolve around lectures and kayaking excursions that launch right from the sports dock. But you don't choose Wilderness Adventurer for nightlife and water parks — it's all about getting an up-close look at the region's spectacular natural wonders and amazing wildlife.
