Something relatively new for people with specific cabins booked is the "Upsell". I know NCL and Carnival do this quite often. They will call you with a "deal" to upgrade to a higher category for a price. Often these are decent rates and nice upgrades. Sometimes they aren't any better than the current pricing.
True for those companies. And Princess is very good at upgrading from a guarantee however they usually only upgrade from same to same just better location.
RCL and Celebrity do not call to upsell. They will upgrade at their cost - not that it happens a whole lot. It does seem to happen more on the Monsters of the Sea though.
