Does Carnival have an onboard booking program?

[jimbug]

Just curious if Carnival does the onboard booking thing like Princess? (Sorry to keep comparing the two, but it's my only frame of reference....) I'd like to pay my $100 pp to keep a future booking open while onboard ship....surprise my hubby with a trip sometime in the near future....

You can book while on board but you won't get anything more than you'd get if you waited till you got home. Many times you can find lower prices at home too.
