Find Your Cruise
You will find in, all probability, that the card has a magnetic strip which will be date sensitive. The same or similar facilities are offered to Diamond and Diamond Plus C & A members and I have never had to hand mine back but also have never tried to re-use them either. Sorry to dissolution you. .......Neil.
'Dissolution', eh? I see your point ...!
If you stay back to back youget new card. magnetic strip has date on.
