Thank you all for your comments! We just booked the Northbound cruise on Island Princess and are very excited. The descision was due as much to date (wanted northbound and the 14th worked better than the 5th), as anything else. Based on your responses, along with reviews from other sites, I don't think we could have gone wrong either way. I will continue to check back on this site to read any additional comments, but will be especially interested to hear from former Island cruisers.
ALASKA HERE WE COME!
