Our plan of attack in Ca Adv is that we go straight to RSR then after we get off that, we go to the FP area for RSR and get a FP for that to ride later in the day. Next we head to Soarin to get a FP, next head up to Grizzly Rapids to get a FP for World of Color. Then we head to Paradise Pier and ride Toy Story Mania and Screamin. By the time we are finished with those, it is time to get to Soarin for our FP. This way we hit the headliners and still have a FP for RSR later in the day.
Keep in mind that RSR and WOC are not linked to the FP system so that is why you can still obtain the FP for Soarin. Toy Story does not have a FP. Not sure of the ages of your family. But the Aladdin Show is amazing if you have time or interest in seeing it. Animation Academy is also a favorite of my kids and is a nice way to cool down.
For lunch, you can go to the exit to the Grand Cal and head to Whitewater Snacks. We love their Nachos and Carnitas Burger. It isn't very crowded and the prices are decent for
Disneyland.
We are DL locals, well an hour and a half away, but get there monthly. We also own at the Grand. Feel free to ask any questions.
