We all worry about these things don't we?
Last year my passport was damaged a little bit and I got all concerned. On this site some told me "when in doubt get a new one" ...so I took their advice and showed it to the post office passport guy. He said "No...you don't need one". I didn't take his word for it and then called the passport number and was told " you should be fine" and given another number to call if any problems arise. Not taking their word for it I returned to the post office and ask another window clerk for a new one anyway...."just to be on the safe side" . He said "NO...you don't a replacement"
Even my Mom got angry with me worrying.
It's all apart of cruise anxiety.
