Ardis, part of the problem is that the offers are for combinations that are not advertised initially. Therefore, you can book a wonderful cruise for May only to find that you could have had the cruise for half as much in October. Or, you have booked your Asia flights for your two segments only to find that they are the wrong segments that are discounted. Of course, by the time these specials come out, you are in the severe penalty period on your booked cruise.
