Is there a time limit on how long I can stay connected to the free Wi-Fi hotspot?

In order to enhance user experience on the Wi-Fi, various timeouts have been put in place.

a.    Redundant sessions will be time out after 30 minutes
b.    Idle time is 5 minutes
c.    Cookie time 1 day [after user sign in, the session is stored in the system for a day from the time of login in]
