LGYC provides members with internet service while at the club as part of the annual dues. The system has been upgraded over the past couple of years, and should now provide reasonable coverage over most of the club property, particularly well at the clubhouse and the docks.
With your connected device, go to the WiFi connections and find the LGYC WiFi network.

The clubhouse and docks have different repeaters with the same name, so this should work anywhere at the club.
