Only reason I know about the Early Saver is I am booked under that. The drawbacks is it is a non-refundable/non-transferable(to another person) deposit any any change in ship or itinerary is a $50 per change. I had to change my ship and itinerary once resulting in a $50 change, but it was worth it as the other cruise cost far less and I was strapped for cash. Changed from a 7 day Eastern Caribbean to a 4 day Western Caribbean, but since it is my first cruise the legnth doesnt matter to me. I will be taking a couple in 2010 as well(yet to be planned) anyway, so no harm no foul.
