Anybody had this happen and any advise to in getting a refund or on board credit, at least?  Booked through expedia who sent me reminder emails but they got lost in my hundreds.  No call, no letter, no email or any contact from Carnival directly which seems a bit off.  A 2 minute phone call would've resolved the situation but instead they auto cancel me and I have to re-book at extra $600 or lose my $600 deposit.  Strange the $600 extra ticket price is the same amount as the deposit huh?  Very unfair...speaking the "supervisers" at both Carnival and Expedia I am left thinking I will have to dispute the original $600 deposit via my credit card company on grounds of a completely unethical business practice.  They didn't even offer an upgrade or credit of any sort whatsoever. Great service from the fun ships.
