We are planning on May/June 2020 trip. I’m so used to knowing what to expect (cost wise) with WDW. How on earth do I make a budget? How many days will be a good amount? I read somewhere that you really have to allow yourself time to adjust for jet lag? Is $9000 a good budget? There’s no meal plan available, right? There’s 4 of us...2 adults and 2 kids (13 and 9).
