Questions that should be asked -
Are the AP’s centrally Managed? If this is yes then the central control software will have the relevant logs if it is set to log them.
ir No well are you using a seperate DHCP server for the OPEN network (please say yes) if this is the case then you would have the DHCP server log the IP’s , MAC addresses etc.
If you are not seperating your normal network with your open then I must warn you this is a huge issue with security. A seperate Firewalled network model would always be advisable.

Most wireless APs have a logging option. If they support SNMP, you can forward the traps to an SNMP logging server. Checking the local logs per device is do-able, but time-consuming. Best option is to have the devices report their logs to a central server…
