HAL's site is not very easy to use. You have to keep clicking through a lot of stuff to get where you are going. Try this:
hollandamerica.com
THEN: site index
THEN: 5-star cruising
THEN: our fleet
THEN: rotterdam
THEN: 2002 sailing schedule.
THEN you will get a pop-up with a multi-colored schedule
THEN go to your TA and book them all
(here's how to book all of them: rob a bank, a really big one. Take all the cruises you want. Eventually, they will catch you and you will end up in prison. But think of all the nice memories you will have for the next 10-20 years!)
