My husband and I enjoyed our Infinity cruise May 27, 2007-June 3, 2007 very much. The Infinity is a beautiful ship, and you truly cannot beat the Inside Passage for scenic cruising. We loved the artwork throughout the ship. We are young professionals in our late 20s, and this was my husband's first cruise.
Note: We took the bus from Seattle to Vancouver b/c flying to Seattle was so much cheaper. This worked out for us, b/c we got to explore Seattle a little on both ends of the trip. However, if we had it to do again, we might have just paid the extra to fly to Vancouver. We'd have to run the numbers, but we wonder if the extra cabs, etc. our trip from Seattle to Van. necessitated negated any savings.
Embarkation - We stayed in Vancouver at the Holiday Inn Vancouver Center, which is not the greatest hotel, but I got it on Priceline. Our documents told us not to arrive at the pier until 1:00pm, so we spent the morning before the cruise walking around Vancouver, including to Granville Island. It was beautiful. We took the hotel shuttle to Ballantyne Pier and were onboard by 2:00pm. Waiting for customs takes some time, but not too much, and it's par for the course.
