Internet access for for Guests network can simply be throttled so main network will not be impacted by heavy users visiting your house.
First we create a limiters for "In" and "Out" traffic using a Traffic Shapper:
Firewall -> Traffic Shaper -> Limiter

Click on "In" and click on Enable, give it a name and choose the bandwidth that will fit your needs:

repeat the same for "Out"

Then go to Rules:
Firewall -> Rules and choose "Floating" rules:

Create rules for "In" traffic:

Select proper Interface, direction, Internet protocol. It is best to use Alias for Source to properly target IP's or network.
In our case we have selected every IP connected to the Guests interface.

in advanced features select proper queue order. Keep in-mind In/Out reversed there.
Similarly create "Out" rules:

Do not forget to apply changes for rules to take effect.
