I need Help on VLAN & Hotspot

Dear All
Now I face a big trouble with VLAN & Hotspot, need your help:_)

One of my customer is an hotel, and using the hotspot to support Plug&Play for guest.
And now,the IT gays want to using VLAN to separate each room to prevent ARP virus attack eachother.
Now, I need setup VLAN Interface for each room,and setup address for each vlan interface and setup a lot of hotspot for each vlan interface, as you know, the hotel have over 400 rooms,so i become crazy,
I have no ideal now, Does anybody can help me about this, very thanks…

I have think about as below:

VLAN Interface — Bridge(with IP address) – Hotspot on Bridge

Does this working?
