As far as pictures, here's what the photographer shared with me:
I will pass all of the information in this thread onto the photographer and business owner. What it sounds like is there's probably more information available that's hurting the potential listing (no street view, conflicting addresses, not registered with ALOA) than what's available to help it get published.
As for the open door, all GBP tours are required to have what's called a "10-4-4" series of pano's that start 10 feet outside the business, then go to 4 feet outside and finally 4 feet inside. The door(s) should be open for these three shots. Only in rare circumstances will this not happen because of proximity to the street or because the business is in a privately owned building, or something like that.
As far as I know they've created a listing but it's in the process of being approved, so it's probably best for me not to even attempt a new listing through MapMaker.
Thanks again for your insight into this issue. And thank goodness we'll have all of these posts archived and searchable when we switch to the new forum!
