Should I just make two plans, a morning and evening or is there a better way?
You can put a 3-4 hour break into your plan.
Okay, thanks. Hopefully, when I optimize, it won’t put that rest at the beginning of the day. 
It shouldn’t but I am tagging @brklinck because he is the expert !
You should be able to set the time frame for the break and whether you’re leaving the park or not.
Rest breaks have a set time and duration, so the Optimizer does not move them.
Great. I remember several years ago getting my rest at RD, which I thought was weird. Maybe that had been a glitch or I had set it up incorrectly.
Thanks for confirming.
I started out using a break but having to give it an exact number of minutes kept throwing off my plan as our last pre-break activity time kept changing. So I ended up inserting a restaurant at 5 pm with a note that this was our return time to the park.
