Film Fair is a lot different than other SM shows, they are a lot smaller and the guests are normally a lot older, Queues are never really long. If your not doing photos then you can find you can get everything within an hour, 6 items should be ok, But just remember if queues build, then do a few and return when the queues are a lot less. Also I wouldn't turn up in Cosplay outfit as you will find you will be the only one. Hope this Helps
