My wife and I have booked a round trip cruise from Rome (4/23 -5/3/14) and have been shopping for flights to Rome. I have seen some attractive air/hotel package deals and was wondering if it is possible (and affordable) to extend the tour return flight date. We will be visiting friends in Naples after the cruise and hope to spend about 45 days in Europe. There are some great packages that would provide extra days in Rome before the cruise for about the same price as a round trip ticket alone - if we could select a later return. Am I dreaming or is there a way to do this? Any suggestions?
