That is ok and the right way to approach it. If you get a guarantee that you can get on your favorite ride quicker that that is absolutely correct, however, those that say that they save time overall in a day is incorrect. If they ride nothing but FP rides they will indeed save time and see what they want to see, but if you are like me and enjoy all the attractions, I will still attempt to get a FP for my top favorites, but I know that I'm not doing that to save time in my days visit. I will leave knowing that I saw what I wanted guaranteed, but I will not see more because of it. Chances are I will see a lot less then I would have if there was no FP anywhere.
