Actually, just to be clear, the maps used in the Map Wizard and the Advanced Maps are custom to RoadTrip America and we don't use any of those generic icons (like the red circle by a bed icon.)
Edit: Ah, yes, it is true that one can scroll in and see those icons, but RoadTrip America has no influence on what motels are shown. At the point of scrolling in, those motels appear on the map pane because they pay a fee to Google Maps.
Whereas the lodging options identified by the White Flag with the "L" indicates those establishments that we recommend and have visited and written about.
The attractions that are visible on the Map Wizard and Advanced Maps pages were identified by bonafide roadtrippers who personally visited them and wrote about the places. And there are several "Lodging" options, but they tend to be unique lodging experiences and not ones found as part of chains on the major roads.
As a member, you can use the Advanced Maps options and search for Lodging attractions that we have written about.
Mark...and I apologize to AZBuck, he was accurate with his comments. I had never noticed, because I don't use the background images that are on the Google Maps.
