What I don't like is:

If Geocaching HQ determines your event meets the requirements for GIFF Weekend, you will be provided with the file containing the GIFF 2015 film reel and your event will be added to HQ’s bookmark list of GIFF Weekend Events. If your event is not approved by Geocaching HQ, you will be notified. We recommend you then notify your guests that you will not be showing the GIFF 2015 films.

So, you have gone to the trouble to find a venue, organise the event, sort out the equipment and then GS say no
