Given there is an almost two week window between the 4-night sailing from Vancouver ending and your cruise departure, I would say it likely will be going into the shipyard for refurbishment.
I got a note from HAL that it would be in dry dock for 2 weeks, then a 4 day repositioning down to San Diego...and a 7 day shake down to the Mexican Riviera....then PICKING ME UP IN SAN DIEGO AND GOING TO HAWAII:-)....Opps didn't mean to shout.....
What is good about that timeline is that the people on the 4-night repo cruise will identify any problems resulting from the refurb, so you should have a nice clean and updated ship for your Hawaii cruise!
I wish I could, but I am working a consultant contract through January at "Ye Olde Nuclear Plante". They agreed to let me take the Rock Legends cruise in December as a stipulation in the contract, but otherwise I am locked up as far as vacation time.
