Room Availability Feature

Right now I have the availableRooms activity auto-refreshing. The only issue I know of is when the user clicks on the Create Events button and clicks back to get back to the availableRooms activity. At this point the timer was canceled, but when the user goes back the timer doesn't restart. So, should we have the activity auto-refresh? I have a refresh button implemented in the comments already if that's any better. Or should we even have a refresh option?
