Hi, Brian Jakovina
Welcome to Google Maps Community Support Forum & thanks for your post.
When the AI senses booking information, that creates the travel plan automatically.
You can edit the plan
Additionally, you can create new plans in the utility. The page will show nearby attractions. You can add those to your itinerary and create a route plan.
