Linda: I agree. Many of the gems are in the comments. I'm still working through them.
Cripes: In the responses to the very first question, Lisa Kolb of Acorn through out a "mind blower" from my perspective. She knows the hospitality industry and more specifically B&B's. She referenced that ranking in the pac/maps is highly dependent on having bookings with OTA's (On Line Travel Agents//hotels.com/Expedia).
I had found a resort city where an awful lot of hotels had neither joined or disconnected from the OTA's. (they hate them).
When I did a maps search on HOTELS (city name)... 19 of the highest ranked hotels were all connected to the OTA's and in the next 20/ 16 of them were connected to the OTA's. I'd checked that city in the past: About 1/3 did not have OTA connections.
Wow. Lisa suggests that the Maps rankings are heavily influenced by financial concerns as Google has a financial connection to the OTA's.
Now that is a very big find.
The Gems are often in the comments. Keep going through them.
