I'd think if it was hard frozen before and kept in anything even semi insulated it would be fine for a while. Worst case ice it down at the hotel on the overnight. Unless it has to be lugged around until day 11 of a 12 day or something, I can't imagine dry ice would be even remotely required.
I bring frozen items often. They will keep at least 48 hours in a cooler with no problems.
