any park and any RD - be smart about it. I went in the firs week of May and took advantage of morning EMH for each day even if it meant go to the park that was not "recommended" by Josh.
My reasoning was simple - I would rather push 2 strollers at 8am than 9am due to the heat. I also planned it a little bit based on park map and walking distances. nothing crazy - but simply have an understanding which ride first, second, third etc.
Example: MK with morning EMH. since only FL and Tomorrowland are open - you get almost 2 rope drops for the price of one. counter clock direction - Pooh, Mermaid, Small World x 2 between 8 and 9am. at 9am we moved to BTMR x 3, and than PC and JC --- JC had about 10 min wait time. we closed the first 2.5 hrs with magic carpets of Aladdin with about 15 min wait time around 10:30am.
than we had our FP+ scheduled for afternoon part of our day.
Epcot is another park where a little planning can get you a lot done. same approach - 8am EMH and we walked to the land building and did Soarin first at 8:20am with about 20 min wait time, than same building - the Land boat - it was a walk on at 8:50am. We walked to the Nemo building and Nemo was a walk on at 9am. after Nemo - pictures, tanks and we waited for the first show of Crush at 9:30am --- suggestion - be at the entrance around 9:20am since they let people in early. at 10:10am we had first FP+ for the TT. My hubby went with our older son while I waited. at 10:40am - we walked towards Norway. We did Maelstrom at 11am with about 5 min wait before the ride opened.
than we waited 10 min for our lunch at Akershus at 11:30am. than used remaining 2 FP+ for other rides in afternoon.
Not all rides we all could go on together since we have 2 yr old in our party. so it was either me or my hubby who took our older son on rides that required 40" to ride. Yes, we also got baby rider swap passes too for afternoon rides.
My final suggestion - I wouldnt count on extra FP+ for Epcot or HS or even AK. this strategy may work in MK on certain days - but you may be surprised with availability in smaller parks.
HS - if you have small kids - dont use FP+ on any "shows" --- if you arrive 5-10 min early - you may not have a great seat but you will be ok. kids will still enjoy the shows.
If you go in the summer time - treat lunch break almost like a break from the heat and simple rest than your lunch. even in May we needed to get away from the heat.
print out the map of the park and mark your journey in the first 2 hrs of the park time if you do morning EMH. it will help you a lot.
