If you were considering this you might want to look at HAL's Statendam return SanDiego instead.
Departing from and returning to Ensanda gives you 6 or so hours of bus rides to deal with. Probably worse than flying to or from Honolulu.
Another option would be to join us for the CruiseMates Lets Get Lei'd cruise, Honolulu to Vancouver. 5/13/02. A great bunch booked so far! Here's a link to the info.. <http://www.cruisemates.com/Articles/CMcruises/summit.cfm>
