The parks won't be "holiday" crowded, but most schools will still be out, so it will definitely be busy. For the AK/HS days, if you are splitting the parks up in a day, and hitting AK RD, then I would FP at HS. For MK, I would do RD, FP later in the morning and get extra FP for evening, after you have used your 3. I am having a really difficult time planning our Epcot plan, as I'm not sure what is going to be FP, as far as the Frozen M&G/FEA, and whether or not TT and Soarin are going to remain in Tier 1. Our June plan, for now, is to RD, stand-by either Soarin or TT, FP FEA for around 10am, if possible, and leave TT or Soarin and go do stand-by for the M&G, ride FEA afterwards. I have not decided what to do about the other TT or Soarin that we can't FP or hit at RD. My brother and his family are only going to be with us at Epcot for 1 day and it is really difficult to fit it all in, again, assuming all stay Tier 1. We might have to RD both TT and Soarin because FEA is a MUST!
