Using RB951Ui-2HnD as HotSpot Captive Portal authenication

I cannot find an adequate answer to my specific question. (New intro, right?)

I am the IT manager for a hotel and the property manager wishes to charge/control the wireless Internet access - HotSpot captive portal.

We have used pfSense for years and wanted to deploy it with DMA RADIUS Manager but it lacks some functionality - details not relevant here.

Can I use several RB951Ui-2HnD APs each connected to the DMA RADIUS Manager server as a different NAP to provide the HotSpot Captive Portal function throughout the location OR will I require a Mikrotik router AND APs?
