Hardware :: AEBS On Company Network (with Guest Feature)

We're looking to install 3 WAP in our new office. The alternative to a AEBS set up would be Cisco's WAP4410N WAP. It's a smaller office (about 35 people), but we'll be divided amongst three floors, so 3 separate devices. It's a PC server with mostly PC devices connecting to the wireless network. I'd like to have an integrated wireless network, which I know the AEBS can do. I also like the dual-band function of the AEBS, since there are plenty of older machines that are used in the office. But what I really like about it is the Guest feature.

Our clients are usually just allocated to one area (like conference rooms) in the past, but now they are somewhat dispersed through out. Having the Guest network extend everywhere that the Company network is would be great, and we wouldn't have to buy secondary WAPs to do this. However, the router/firewall function would have to be turned off on the AEBS so that our main DC was still handing out IPs, and I don't know if this or bridging the three AEBS together would remove the functionality of the Guest feature.
