I didn't know where else to post this so I'm asking you guys. Is there a difference in "trip protection" and "Vacation protection". I'm cruising to Alaska in September. The invoice I received from 'Cruises Only' says that I purchased trip protection thru Travel Guard but while I was looking thru the travel summary it said vacation protection not purchased. Are they not the same? If not, what's the difference. If they ARE the same, why does my invoice say that it was purchased but the travel summary says it wasn't?
