Postcards can be mailed each day when the ship is in port. Due to customs regulations, any type of mail other than postcards, cannot be mailed from the ship; of course, letters and packages can be mailed from a local post office in the ports-of-call.
The postal regulations of the various ports require that the postcards be stamped with a local stamp only (no U.S. postage). The Guest Services Desk sells local stamps.
There is a mailbox located at the Guest Services Desk; one side is for postcards with "Foreign Stamps"; these postcards will be mailed when the ship docks at the appropriate port-of-call. The other side is for postcards with "U.S Stamps"; these postcards will be mailed from a U.S port only or when the ship returns to the U.S embarkation city, whichever comes first.
