I have read a few posts re this but need to clarify. We are going to WDW prior to our cruise and will have a few individually wrapped/sealed goldfish, granola bars, etc. I think I am correct in reading that if we don't use them all at WDW, we can take them on the cruise and carry them back home as long as they remain unopened. Is that right? Or should we just toss what's left before cruise? I don't see us needing them on the cruise. Thanks.
