The strategy Aimeedyan mentioned is best. Make fp 30 days out or as soon as you know you’re going, if it’s a last minute trip. Make your fp back to back, with the first one starting by 10. Don’t use your first fp till towards the end of the window, unless everything nearby has a wait time of more than 15 minutes. The first hour the park is open, you can easily get 2-4 attractions done. After you use each fp, if the window for the next one hasn’t opened, refresh on the app under the modify option until something comes up. As soon as you use your third fp, book a fourth. When you use that, book another, etc.
(The refresh strategy means you go in to either modify an existing fp or look for a new one and keep selecting a different time, like changing back and forth from 10 to 10:30, to get the available fp to refresh. People are constantly cancelling fp the day of; you just need to check for fp at the right moment to snag that perfect time or the hard to get attraction.)
Don’t wait for anything more than 15 minutes, except maybe Peter Pan as the queue is fun. It’s a waste of time. Just refresh until you get a fp. MK is the one park where nearly everything you do, you’ll need a fp after early morning. You don’t need a fp for any of the shows; just arrive 10-15 minutes before it starts and you’ll get a seat, unless it’s a crazy busy day. Unless you’re going on an extremely high crowd day, don’t bother with fp for Philharmagic and Muppets. It saves you no time; everyone is just waiting for the next show to start.
Even if you would like to take things slow and take in the detail. I still recommend going at a fast pacd the first hour or so after park open, especially at MK. Wait times are generally short for most things the first hour.
If you’re not familiar with the maps, attractions, entertainment, and character meet and greets, it’s a good idea to look at all that before you go. Since you’re not local and won’t be there frequently, you don’t want to waste time getting lost or doing things no one has interest in.
Get first time visitor buttons for your children on your first visit! They’re available at ticket counters, guest services, and sometimes a cart on Main Street outside guest services at MK.
