WDW for the first time in forever (or about 9 years)

[DisneyDreamer3090]

Hi all! I am currently in the very early stages of planning a WDW trip for January 2021. Early I know but I am planning to do the half marathon when I go, I’m a beginner runner so a trip to Disney is a big motivator. This will be a mother daughter trip and only my 3rd visit, we are from Australia. The last time I went was in Jan 2013! I know it’s still a while away but as trips to WDW are so expensive, we want to start budgeting now so we can do everything we want to in our visit. Just wondering if anyone has any advice for marathon weekend/dining options that are can’t miss or any other recommendations or suggestions! I have attached a picture of our (very rough) outliner plan. Thanks
