This seems like a good deal if visiting twice over 18 months. I've never been to UO, but been to WDW many times. We are planning our first UO trip in June of this year, and we go to WDW twice a year, so we could stop at UO another time or 2. We are considering the preferred pass (which is their 3rd tier) because it comes with 18 months, and because it comes with Park-To-Park Admission (I would need this in order to ride the Hogwarts express train, right?). The 18 months would fully cover 2 summers (and we have off over the summer). The only reason I'm even hesitating is that we have never been there before, so it seems reckless to buy an AP for a place we don't even know we will like. But we are big Harry Potter fans, (and love WDW), so I think we will enjoy it!
