We saw Wishes twice on our last trip - first time from between Casey's and the hub and the second time from the area just left of the castle (headed to Adventureland). The more "center" you are with the Castle, the better your view will be (the fireworks just don't happen "over" the Castle, they happen "around" the Castle - in a very large sense of the word). Some have suggested the best area is near the flagpole/statue of Roy and Minnie near City Hall - you wouldn't see Tink from there but you should have a great view of the fireworks. From the hub area, you should be able to see Tinkerbelle fine. Any way you go, I would stay close to Main Street and you will be amazed......
