So when I was young and stupid (1993) I was charged with a DUI in college. The state I live in does not allow DUI's to be expunged from your record. Am I correct in understanding that if I book an Alaskan cruise that I will not be allowed to enter any Canadian ports? And in fact will not be allowed to cruise at all if the ship has stops in Canada? I've read that the appeal process through the Canadian government is lengthy and expensive. Just wondering if anyone else had dealt with this issue.
