Personalized Touring Plans Question Re: Rider Swap

When creating my personalized touring plan, if I am planning on using Rider Swap, do I have to say that I’m planning on riding the attraction 2 times, or does the fact that I’ve chosen Rider Swap work in two rides automatically into the plan? Thanks!

Last time I used it in a plan it doubled my estimated time plus a few minutes. So think its automatic. Try it with and without ride swap ticked and see what happens
