Do I need vlan Pooling Or No?

Our current wireless network is Cisco and we have a secure SSID for our school owned devices and an open SSID that employees and staff use with their personal devices.  We are planning our Ruckus deployment and I am trying to decide if I should use vlan pooling.  It seems like it would limit broadcast traffic that could be a problem with a single large vlan but I wonder if it could cause issues with something like AirPlay if the AppleTV and iPad ended up in a different vlan.  Currently we have around 100-150 devices on the secure network at a time and at peak times we may see around 1500 on the open network.  We will be splitting the BYOD networks up where staff and student are on different vlans or vlan pools.  Should I use pooling or just go with single vlans?  I am planning the following:

District owned devices
Staff BYOD
Student BYOD
Guest
Onboarding

I may put the BYOD all under one network and use different vlans/pools and user roles to determine what they have access to based on how they logged in through Cloudpath.
