How big of a rolling suitcase can you take onboard yourself ?

Yes, our small airport in Burlington has them out in the open too. But those are behind the ticket counter and the scanners used for carry-ons is at the check point. I believe that in the terminal Carnival only has the carry-on sized scanner, so I'm not sure what their protocols are for handling the full sized luggage people have to carry on if they are there later in the process.

I would assume that there is a full size scanner  on the ship itself.

I would, too. They have to have some way for scanning those late arrivals and carrying it with them would make the most sense.
