Ok… so there are two buttons – Optimize and Evaluate.
If you press Optimize then Touring Plans will completely rearrange your plan to give you the most “optimal” sequence of rides for low wait times.
Evaluate will keep your plan the way you’ve arranged it and update the current waits. I make personalized plans. I don’t like crisscrossing the parks just to save a couple minutes. I want my plan to stay in the order I’ve arranged it to save walking.
At the bottom of the App you will see multiple buttons – Home / USF / IOA / Plans / Chat / 10-day
If you press the button for whichever park you are in you’ll see the up-to-the-moment wait times – including Single Rider for all the park attractions.
I only press “Plans” to see the order I’ve put the attractions in. I press “Done” to clean up the screen. This is all I, personally, do with the “Plans” portion of the App. It is possible to press Evaluate to see the new wait times, but you have refresh & it’s too easy to accidentally press “Optimize” and my plan gets out of order.
I prefer to just select USF / IOA to see the wait times. It’s faster and my plan doesn’t get messed up.
Any more questions, just ask!
