InnerSea Discoveries is offering a $100 shipboard credit to those who book one of three “Alaska Unleashed” departures in summer 2013 by Jan. 11. On these adventure cruises, the Wilderness Adventurer guest capacity is slashed from 60 to 36 guests. The departures are meant for active travelers who like to go on full-day adventures. The line recommends that guests choosing an Unleashed departure engage in regular weekly physical activities equal to 25-mile bike rides or five-mile runs or hikes. Sailing between Juneau and Ketchikan, the week-long adventures depart on June 8, July 13 and Aug. 10.
Cruise fares start at $5,595 per person based on double occupancy. Cruise rates include transfers and all activities except optional excursions. Port fees of $175 per person per week, spirits and gratuities are extra.
