I agree, for some routes a single round trip can pay for Discount Den. Also, you only have to book the trip when you are in Discount Den to get the reduced fare, the actual flights can be beyond the expiration date. We did this last year, booked flights for four to Orlando and it was set to expire in March, in January or February we booked flights to Cancun for May, which was past the expiration date of our Discount Den but we still got the special rates.
