Since you're going in the summer, if you want to see as much as possible, I strongly recommend RideMax ($17, but well worth it IMHO since it saves you at least 2 hours a day, for $3/day). Here's what we do:
Note that step 6 (getting your Fastpasses) should be done 30 days before the first day of your trip (at midnight of that day if you want to get Anna & Elsa meet and greet, Seven Dwarfs Mine Train, or Toy Story Mania). If you're staying at a Disney hotel, then you should get them 60 days in advance.
1. First, choose "which day/which park", based on the easywdw calendar. July calendar is
here.
2. Select all the rides you want to do in each park (regardless of Fastpasses). Wikipedia and other sites have the rides for each park. YouTube is helpful for a preview if you're not familiar with certain rides. Also note that some rides have height restrictions, which are strictly enforced.
3. Of the rides you want, "assign" your 3 FPs (for each park) based on
mesaboy's list.
4. In RideMax, select FP attractions (but not times) (Note that RideMax has tiering built in.) Also add in your dining reservations, and it will plan around those.
5. Then in RideMax, select the rides for each park. RideMax will generate the touring plans, including FP+ times. Ridemax will also tell you if you can't fit all your rides into your allotted times.
6. Then get on
MDE to select the FPs, based on the FP times in the RideMax schedule. (after you pick your 3 FPs for each park, you can usually modify the times)
