Tough choice. We usually flip a coin because they are two of our favourite resorts. Or we choose the one we haven't been to most recently. If I was doing one of the backstage tours at AK, I might choose AKL. If we were doing a hard ticket party at MK, I might do WL but other than that, I find it difficult to choose. Usually it comes down to availability, If equal availability, then the other techniques (coin, alternating, evening ticketed/tours) kick in.
