As a resident of Southern California and a regular visitor to Seattle, I've spent time in the San Juan Islands and up and near Vancouver/Victoria. I had heard about the Princess Louisa Inlet and decided this was the year to explore.
This was my 3rd Un-Cruise, a company I love and remain very loyal to. I was skeptical about the small size of this vessel and the 22 guests onboard knowing I really enjoy 50 - 75 people on these small ships. I was in for a big surprise. I had a blast. The very small group allows you to really bond and jump from summer camp for adults (which has been my larger small ship experience ~ vessels under 100 guests) to bonding as a family of strangers. The group consisted of a varied age group from 50 to 80. Since it was September (and my favorite time to take off to avoid lots of kids), I knew the age group would be older. The great thing about these kinds of cruises if that you get to know everyone very quickly. Those of us who are high energy, very adventurous and want to exert energy found ourselves being cheered on by those who have either had their day in the sun or simply don't want an overly physical trip. It's all available here.
Embarkation was a breeze. Be at the designed hotel is downtown Seattle by the assigned time, go to the hospitality suite, ditch your luggage and transfer to the ship. Easy-breezy. The hotel is located in the heart of all that can be found on foot downtown. A ten minute walk to Pike's Place Market, a three minute walk to the Nordstrom mothership and a 15 minute walk to the REI flagship store. Lots to do and see if you arrive early and have the full day to explore.
