Have you downloaded the new
Disneyland app? It seriously helped us navigate and decide if and when we were going to use the standby lines or Fastpass. I also used, for the first time, Ask Otto - their automated phone service that let's you say the name of a ride and it will tell you how long the standby line is, whether there are Fastpasses available and what the return time is for available FP's . The number for Ask Otto is on the Times Guide they hand out when you enter either park.
The RSR FP'S are a bit tricky still, they aren't running out as quickly, but they stop distribution if the ride is temporarily down. I'd look at the time when you pass the FP distribution spot, near the entrance to Bugs Land. You will probably be looking at an evening time slot, but the ride is awesome then! If you are able to avoid the entire area until evening, it all looks better at night!
Screamin has FP available, but I don't love the trek to the Pier area, so wait til you are ready to explore the whole area in the Pier to grab those. Toy Story is down there and has no FP line, so it's standby for all! Anything under 30 minutes is considered a reasonable wait for this one! Grab a drink and a pretzel for the line!
We observed that Soarin FP'S only allow you to skip the outside portion of the line, so if there is no outside line to wait through, you'll have the same advantage as FP holders. Same with Indiana Jones in DL! You just merge right away with the standby line.
Aladdin is a great show and I just couldn't make myself prioritize it on our last trip! Good for you if you get to it on the first day!! Hmmm, maybe after your lunch at Carthay Circle?
Have fun planning!!
