You can always find information on the respective cruise line web site. You need to navigate to their News page. You will almost always find out what the line has in store for their ships and any other current news, as it relates to the itineraries.
You can also find information on this site from articles that are generated almost on a daily basis.
The only information I have is on the San Francisco port schedule, and if a ship is planned for drydock here, it'll show in the schedule. I see the Sun is scheduled for September 22 for a week.
You can check other ports' schedules, but I know that's a hassle because you'd have to know where the ship would be refurbished. I guess Star is on the Atlantic side now (I took it in Alaska last September) so you could look at east coast ports, Fort Luaderdale of Miami, perhaps?
Haven't been able to find any info on Princess website. Does this mean the Star won't be dry docking this year? I did read that she will be getting the Theater Under the Stars, so maybe that will happen before Fall.
We are hooked, but not booked Can't wait to cruise again!
You just need to see when an empty week is like it looks like the grand is going in the first week in november, personally I doubt the star will be in for a refit anytime soon she is only 2 years old and it wouldn't make sense to pull a 2 yr old ship out of service , looking at princess's posted schedule through sept 2005 doesn't look like she'll be out of service to at least then.
It is quite possible that the installation of the movie screen can be done without a drydock.
On many occasions the cruise line will take on the equipment/parts and the installation crew to accomplish the work during a cruise. This might be a slight inconvience to passengers, but they would not have to loose the revenue from drydocking.
