DTW-MCO standard NWA awards during low seasons (September, early December, ...) aren't that hard. During high seasons (Feb, March, and much of summer), well, they are just about impossible.
The trick with award miles is that they are much easier to get for less popular destinations more or less year-round, or popular destinations but at less popular times. I've earned nearly a half million on NWA, and have used about 400K of those, all on standard awards only. Whenever we have a leisure trip coming up, I look into using them, and can about 2/3 of the time. About half of those instances, it ends up cheaper to just pay for the flight. My break-even number is $250---if the flight costs less than that, I don't bother using miles. I also sometimes use them for "gee, wouldn't it be cool to spend a weekend there" trips. For example, I brought my daughter along with me to Paramount Carowinds for a "dad/daughter weekend" on a standard award (I was flying on a 1-2-3 Free ticket that was set to expire.)
By definition, most people are in the majority. So, if you are looking for one *specific* trip, chances are fair to middling that your trip is to a popular destination during a popular time, and that makes it harder to redeem.
