After you get the RSR FP at rope drop, I would avoid Cars Land and focus on Toy Story Midway Mania and Paradise Pier attractions first. The majority of guests will head to Cars Land first. The minority will head to Toy Story Midway Mania first.
The RSR FP now lasts until noon, but lets say 11am-1130am to be safe.

If you can get most of Paradise Pier (TSMM, Screamin, Fun Wheel, and Goofy) plus Soarin and Grizzly done without FP before you use your first FP for RSR you will be set for an easy day. Then before you use your FP for RSR you can get a FP for Anna and Elsa (disconnected FP) and the a 2nd RSR FP.
Symphony Swings, Triton Carousel, JellyFish, Zephyr, and Mermaid are all Paradise Pier attractions that have low wait times times or fast loaders throughout the day.
