I would definitely consider submitting the individual points of interest at the Lodge, or the Lodge itself mentioning those items if you prefer (for example if its difficult to get a picture of the pool etc without being a guest)
And Id submit the churches too as and when I was nearby. Local people wouldn’t need to worry about the freeway probably since they may already be on the correct side
If you build up the area, it may encourage more local players to submit too, and it will grow more from you starting the process. That’s certainly what happened in my area. So you dont necessarily have to do it all
