I have a few Fun Ship Dollar certificates I forgot to use on my last cruise, so I'm planning on using them to pay for my next. I've never used these before, and am a bit hesitant when it comes to mailing it in. Any suggestions on what to do with them before mailing them? I saw that the certificate number is on a cut off paper I can keep, and to send it by certified mail, but should I call them to tell them they're coming? Or should I include a separate note with my name and address? The booking number is on them already.
Thanks in advance
