It would be decent if it worked that way, but what if what you really want is, for example, Splash Mountain, Big Thunder, and Haunted Mansion. When you go in at 7am, it has you coming back at 2pm for Splash. You book that. At 9am, you try for Big Thunder and get a 5pm. Then, at 10am, you try for Haunted Mansion and it’s gone for the day. So is Jungle Cruise, Peter Pan, Pirates, and Buzz. For the rest of the day all you can stack in there is things like Barnstormer, Winnie the Pooh, Magic Carpets, etc.
Maybe this scenario I’m imagining is not likely? But what if it is?
