WDS is just a way to connect APs without wiring them to some common place on the network. Signals travel from one to the other until they reach the router. Limiting internet access depends on what you specifically want to include or exclude. One solution could begin with a proxy server. It's easy enough to find a router that initially redirects to a special website such as motels, hotels, etc. do with guest accounts but a proxy could handle that too.
I have a little knowledge about WDS. and I want to know how to set up a WDS for a coffee shop or a clinic that users only can have to a special website or they have username and password to access internet.
I have been searching about it for a while and I will be glad if someone can help
