Before I buy : NetGear Insight licenses cost for Captive Portal

Hi all,

I'm looking for a clear information and costing understanding before I buy a complete solution for guest wifi in our small guest house.

I'd like to buy a Orbi Pro WiFi 6 Mini set or Orbi Pro WiFi 6 SXK80 AX6000

1 router + 3 or 4 satellites, the whole thing with wifi 6 and mesh based install. (dual or tri band, we'll see...)

The final goal is to have a captive portal for our guests with Facebook Wifi / Instagram Wifi social login connection with voucher.

I understand I need a Netgear Insight Cloud Portal access and buy licenses to manage captive portal options and other features online.

Can anyone confirm if I understand well that the cost structure for 1 site network with 1 routeur and 3 satellites : is going to be 4 APs (195+75€ /year) as shown here :

https://billing.netgear.com/captiveportal?category_id=14&app_id=Insight&continue=https:%2F%2Finsight.netgear.com%2F%23%2FinsightServices&user_type=4

Or is it going to be 1 pack of devices credits (52€ / year for upto 5 devices) as shown in the Insight Premium subscription here :

https://billing.netgear.com/captiveportal?category_id=17&app_id=Insight&continue=https:%2F%2Finsight.netgear.com%2F%23%2FinsightServices&user_type=4

Or is it going to be even different with a 9.99$ / device per year subscription plan as shown here :

Not sure what the price is made of.

Not sure what an AP or Device is (each router ? each plugged piece of hardware, including satellites ?)

If anyone can explain before I buy anything

Thanks
