Hi Kristen! I think your plans look great! I'm so excited for you! I think I would probably do it the exact same way that you already have it laid out. I know what you mean about MK -- and what says Disney better than the castle? But for an adult trip, I say nothing beats an adult beverage and poking around World Showcase- shopping, snacking, watching the concerts etc. Your last day plans should work fine and I think you will Brown Derby.
