Heads up, solo cruisers. Starting August 30, if you want to cruise on Carnival, you’re going to have to fork over more dough earlier in the booking process than before. That’s because Carnival is doubling the amount required as a booking deposit.

Cruise Critic was alerted to this change by member DGP1111, who posted on the message boards, “Starting August 30, all bookings for solo passengers will require a double deposit immediately, rather than just the one deposit that was required for numerous years.”
