HAL lowers prices as sailing dates draw near ( see some of the travel sites such as Uniglobe or CruiseDirections for "Flash Sale" offers). However, the lower fares are nearly always offered to new bookings only. If it's past final payment date, you're out of luck. However, If it is prior to final payment, your TA may be able to browbeat them into the lower rate without canceling and rebooking (In which case you'll likely lose your cabin choice). There are occasinal inconsistencies. In my last experience HAL refused my request for the lowered fare. The date was well prior to final payment and @ 15% less than my rate. However, HAL offered to change my booking from a Cat I cabin to guaranteed outside for 30% less, and we ended up in a much better Cat C location. (FYI, a Cat I is an outside cabin priced at inside rate due to an obstructed view.) I should add that, with a few exceptions, HAL's outside cabins are identical, so a guarantee is often the best value for price. Of course the same is true of inside staterooms if you don't mind the perpetual dark.
