We are going to be there for opening night! Only we will be at Magic Kingdom to see Wishes, as you all know it is going away. Rivers of Light will be a summer show for us, but as Dave said, only through June. We plan on doing Tusker House breakfast for the package, once it opens up for July.
That being said, I think the a dining package is the best best, as we don't now how easy it will be to get the Fastpass+. But time will help with that as well.
