I am planning to visit WDW on 8/6. I will show up at MK around 4:00 after visiting Epcot and HS the first part of the day. If I use my first 3 FP+ at One of the other parks, what kind of FP+ availability will I have at MK when I get there and can choose an additional FP+? Anyone with park hopping experience able to get decent 4th and 5th FPs at MK like this?
