We had similar issues, and have found a happy middle with 40 min max lease time with our controllers (Aruba) having a user timeout of 38 min.

We moved from 1hr. to 30 minutes, but are still running out of leases occasionally. For instance, we have 160 users in a /24, but due to the transient nature of wireless/classes leases that are used for a brief moment the cycle isn't quite efficient enough. What is everyone else using for wireless DHCP lease times? I know I can just add another /24 to the pool, but the networks are not being utilized enough. We want to try 15 minutes but are wondering if we will start to run into issues related with that? Your input is greatly appreciated!!
