Just to be aware (in case you did not realize it), the return time for a show is not an hour as is the case for most attractions. Plus, if you arrive towards the end of the window and you are a larger party...you may not be able to sit together.
Lion King at AK has a 20 minute window. The sooner you return, the more choice of seats you may have within that window.
Fantasmic (Dining Plan or FP+) - check what times they open those seats to the general public - those seats are NOT necessarily held until the close of the return time - better to show up a bit earlier + the pre-show is a lot fun!
