This is a new one on me, and I've done a lot of cruising. I would be tempted to say no, due to very heightened security regulations. They do have short notice lists that they offer to repeat customers, but I've never gotten anything with offers less than 2 weeks. There would be no way they could check you out before you got on the ship. When you look at it from someone else's point of view, would you want to be on a ship that they couldn't the people out first. On the contrary, I have seen boarding denied, as people didn't have the correct documentation, or something was suspicious on the paperwork. Hope this helps, but you could call the cruise lines direct.
