Hello all, just wanted to share that I am visiting Disney World April 7th - 13th too. I hope it's a dead world, except for all of us

. I will be staying off site 3 nights and then Dolphin for another 3. Hope to see some of you!
I have two questions and please feel free to comment if you have suggestions!
1. I booked most lunch or late breakfast ADRs. I left dinners open to be flexible. Is that a bad idea? Should I still book dinner ADRs and only cancel if plan changes?
2. I booked 6-day base tickets, which means I can visit two "lucky" parks twice each. I can't decide between MK (the most popular) and EP/HS (convenient from Dolphin). Which parks will you visit multiple times?
Here is my current plan:
Apr 7th: arrive at Residence Inn in morning, late breakfast at Boma, visit AKL and Disney Spring
Apr 8th: visit AK, lunch at Yak&Yeti or Satuli Canteen (still debating which). Dinner at Sanna. Starlight Safari at 10pm (couldn't get 8:30pm)
Apr 9th: visit EP, lunch at Space 220 RESTAURANT (couldn't get lounge).
Apr 10th: check-in Dolphin, visit MK, lunch at Skipper Canteen, extended evening hours at ?? (Disney is lazy finalizing park hours)
Apr 11th: visit MK, EP or HS?
Apr 12th: visit HK, hope to make early entrance but pending when early entrance is. Lunch at Sci-Fi.
Apr 13th: morning visit to MK, EP or HS? Late breakfast at Topolino's Terrace. Go to airport by 4pm.
