I want to create a virtual world that shows a tourist trail, marked by a virtual red line drawn on the road, surrounded by virtual advertising billboards containing rich text and images. What is the simplest way to do this?

I would suggest using ImageDrawables for the Advertisng billboards. If you have complex text that changes often you can use HTMLDrawables which allow you to draw HTML content inside AR.
As for the red line: we currently don't offer drawing of lines. However you can mark the road with "breadcrumbs" by using e.g. small red circles.
