If you do not require some form of authentication, then anyone in vicinity
of your wireless network will be able to access the Internet for free.

It is safer to use authenticated guest access. You can do this using Windows
2003 IAS and PEAP. Assign users accounts and passwords for these guest users
and then use PEAP (you can use a separate domain which is not trusted by the
other domains). Set the accounts to expire as per your policy; and set
remote access policy at IAS server with the appropriate VLANs or IPFilters.

The clients should be automatically disconnected after the account expires
(as long as the AP supports radius standard session-timer).

The AP must support RADIUS based VLANs or IPFilters.
