Hotspot Security?

hi everyone.
here's my first question. any help would be appreciated.

i have had to implement a wireless hotspot in my friends hotel a month or two before i planned. obviously, this hasn't allowed me the time to study up on the security of the hotspot.

the equipment we are using is:

AP's are colubris cn3200 with cn320 for repeaters
switches are dell powerconnects 2724's which are managed
router is draytek 2950 (their latest enterprise class)

access required is:

1. secure encrypted access for hotel lan & staff. easily implemented with mac & wpa. this goes to vlan1 which allows access to the hotels private lan and internet

2. guest access to just the internet. again, it is easily implemented using dhcp and a https logon with no mac or wep/wpa encryption. this goes to vlan2 which only allows access to the internet.

all of the above clients cannot talk to each other and can only talk to the access point itself. all AP's are firewalled.

the question then......
am i as secure as i can be?

Hotspot Safety for Business Users

We illustrated five common-sense steps that anyone can take to defeat most Wi-Fi hotspot threats. Unfortunately, many users still insist on skinny-dipping in shark-infested hotspot waters. The only reliable way for employers to manage associated business risk is to define, monitor, and enforce hotspot acceptable use policies.

Something old, something new
Many companies have policies governing secure remote access to corporate networks. Those policies and related countermeasures are an excellent starting point for securing business hotspot use. However, they must be extended to deal with risks unique to Wi-Fi.

Before Wi-Fi, remote workers used dial-up or broadband to reach corporate networks. Because those links connected business assets to the public Internet, measures were needed to deflect unsolicited inbound traffic and ensure data confidentiality. As a result, many workers are now required to use anti-virus, personal firewall, and a VPN tunnel when connecting from afar. ......
