@Damienf519 I know this isn't the answer you're looking for (you'd prefer playtesters), but you can playtest your world for routing issues by using Overwatch, which has a setting that'll tell and show you where sims are getting trapped in your world. You would just have to uncheck the option called "Stuck Check Auto-Reset." With this option disabled, the game won't reset the stuck sims, which will help show you where the problem areas are.

Also, another tip--routing issues tend to be caused by routing paint that has holes in it. So, what you can do is scan your routing paint to make sure there aren't any gaps. What will help is to turn off visibility for "flora" and objects in CAW.
I really regret not being able to play test your world, but Island Paradise threw me for such a loop in terms of routing, objects, etc. that I'm still trying to figure out that EP (in terms of worldbuilding) before installing ITF, SN and UN. I'm literally trying to crank out the rest of my worlds so I can finally start moving onto the other EPs.
