Alright r/Disneyland, I need your secrets.

We are going to Disneyland for the first time next week (W-F) and I need to know your best tip, trick, Disney hack, etc. We have our tickets, we know about Fast Passes, we are set for Magic Morning, and I have the app. What is the ONE THING I need to know?!

Need to knows: we are two adults and one 4 year old. He is over 40 inches, but it's unlikely we will be frequenting rides meant just for grown ups.

Thank you for your help!!

UPDATE: Thank you so much for all of your replies! We used a ton of your suggestions and had a great time! You guys are the best!
