My wife and I would like to book a cruise within the last 30 days before sailing, mid to late May. Any suggestions as to when the last minute discounts come out and how to find them?

30 days before, 20 days, 10 days ?

I am an avid priceline.com user for hotels and rental cars but they do not offer the same type of opportunity with cruises.I am very travel savvy after working in the industry but have no knowledge on cruise deals.

Any advice on booking a cruise last minute and suggested booking agencies would be appriciated. So far the best websites are cruise.com and mycruisevalue.com (so far lowest price)

thanks in advance

Last year, we booked our cruise 6 days before it. Got a great deal. Last minute deals, like a week before, or given best through the cruiseline itself.
