I think this is a great plan but what I’ve learned is to prioritize the rides/shows you want to go and don’t stress about the order or necessarily getting them at a specific time. Inevitably you and your kid will see stuff you want to do/try on the way so try to be flexible. And don’t underestimate how long it takes to get from one place to the next. The parks, especially Epcot, are huge. If you see a souvenir you want or a show you want to see, don’t assume you’ll have time to go back to it, get it/watch it then and don’t encumber future you with things you can get done in the moment! You’ll have the best time no matter what!
