Check with them if you are worried. I know some airlines have already begun waiving the change fee.
I did, they're not refunding anything at this point. Personally, I would be fine with a 5 day cruise to nowhere. That would mean two less days I would have to hike around in the hot ass Mexican sun. They will still sail, we just won't get to go to any ports and they will refund 35-40% of the cruise price. We paid $1350 for this fucking thing, so getting a little cash back would be OK.
Also, when you really start looking at it, you get nickled and dimed to death with these cruises. You pay $40-$50 for parking, customary $1 per bag tip to the porter, $50 per person gratuity charge. They take a $100 refundable deposit for your Sail and Sign card. THEN you board the ship. You get fisted like The Prowler on a Friday night on any alcoholic drinks. Soft drinks and bottled water aren't much better. I am looking forward to the topless deck, however.
