While it doesn't hurt to keep an eye on the cruise fares after you've booked, there's no guarantee that you'll see a price drop ( but it would be nice). We booked our cruise with Carnival (for next May) using Early Saver. I've kept pretty close tabs on the prices, and so far, for the category we booked, the price has gone UP $100.00 per person. I'm still patiently waiting for a price DROP. Maybe as it gets closer to the sailing date, if the ship hasn't filled to capacity, there'll be a price drop. If you booked your cruise through a travel agent,hopefully he/she is keeping an eye on the fares and will let you know if and when a price drop occurs. If it's before your final payment, it would simply reduce the cost of your cruise. If it's after the final payment, you would be eligible for an on board credit, and your travel agent will tell you what you need to do to get the OBC.
