BigDad,
Try for the discounts at the onsite hotels, and if you can afford it, stay onsite. The FOTL is SO worth it. I wouldn't even go to Universal if I didn't have FOTL, that's how valuable it is to me. We went at one of the crowdiest (is that a word LOL) time of the year and we STILL never had to wait for any ride, attraction, restaurant, whatever.
I've even noticed that CMs treating the onsite people a little better, for example, when I show my keycard, thay always ask "are you enjoying your stay" or "have a good time" as we went on the rides.
