Get there before it opens as even in Summer you can do a lot in the first few hours. For the more popular restaurants like Carthay, Blue Bayou, Napa Rose you will want to make dinning ressies. Even thing like carnation cafe with their amazing potato soup it is a good idea.
Another place no one talks about that is excellent is Catal in downtown Disney. Not Disney themed but amazing food!
I would def try to do all the things that DW doesn't have for sure. Toad, Alice, Storybook boats, Indy etc. And things that are different like Pirates, Haunted, Thunder Mountain.
Disneyland even in the crowded summer is much more doable in that I have gotten dinning ressies same day or a day before vs having to do the 180 and they still have paper fp so if you get one and immediatley use it then you can get another. Plus I believe they still have the 2 hour window so you can get another one after 2 hours even if you haven't used your first one. So for example lets say you try to get Space but the return time isn't till the evening. If you got the fp at say 10 a.m. for 7 p.m. return then you can go back at say noon and get a new fp for something else. At least it was that way last time I was there. That is another nice feature different then DW.
Def try and see the paint the night and fireworks as they are awesome and you can easily walk to the parks if you stay close enough otherwise there is good shuttles.
Have fun!! We will be there in August as well.
