You are not alone....I work with a number of female competitors and they all say the same thing..."my butt and legs are too big!" LOL
Remember, its virtually impossible to spot reduce fat so you're going to hang onto it in the areas you're just genetically predisposed to. In women that happens to be the butt and thighs. As far as a plan goes, I would simply try to make sure my cardio was kept low intensity for longer times, and any weightlifting you do for lower body doesnt consist of a heavy workload.
