RV park WIFI solutions

I am in the process of setting up a hot spot at this small RV park. I put up two omni directional antennas with a 150n router with range amplifier. I still get three bars and internet out side for about two football fields although you have to see the antenna from where you are at. These metal trailers seem to be a problem. Seems you have to see the antenna from a window in your trailer to get reception. With some rv's and fifth wheels there is not that option where the parking space is. Any suggestions

"Range amplifier" would be worthless. The problem is insufficient signal *from* the clients.

A consumer grade wireless router would crap out past a dozen connected users.

Without knowing any specifics or physical dimensions and layout, the suggestion would likely involve several access points around the park.
