Conclusion
Overall, I like the general design approach of current UniFi Guest Network. I appreciate the option of Hotspot vs. VLAN based guest network creation. If Hotspot limitation is good enough, it is much simpler to create so I recommend that approach. On the other hand VLAN approach involves extra-steps but more customizable. If there is one missing feature I see on current UniFi OS when comes to creating Guest Network, it is step by step tutorial within the app. It would have been more user friendly if we had a section button with Guest Network Creation then asks some questions and based on those they take us to either Hotspot or VLAN based approach.
