Once I logged in a bunch of cruises came up. Including an eight day Mexican Riviera cruise for $549.
My problem is I have a cruise points and I can't use them with this program.
From Carnival's past guest section:
"Here at Carnival, nothing makes us happier than to see our past guests back on a "Fun Ship" cruise. That's why we're offering select sailings from only $199* plus a FREE stateroom upgrade when they book their next cruise by March 31, 2008."
I didn't see any sailing for $199 the lowest is a 3 day to the bahamas for $229 that is quite low. It's not worth it to me cause I would have to fly. However, a 4 days Mexican Baja cruise is $279 so that is more doable.
