Depends upon what they need to do with her while in port. A really dedicated port crew can do some inspired things when given the orders. By the time she sails, she will have been in port for 2 weeks, and you can do a lot in 2 weeks if you HAVE to do a lot in 2 weeks.
Normally, you might do some repairs, but if all you've got is 2 weeks, you merely REPLACE. You re-stock. You load sensitive gear that you don't want to ship separately into the theater. And you give your finely-tuned crew two weeks of holidays with their families. 30 knots for 24/7 and you're back in theater in a week before the opening scene of the feature even begins.
These home port crews take tremendous pride in being able to do the impossible without breaking a sweat.
