We actually had a party in Belgium in 2013 (Oostduinkerke), conference style.
If you're looking at venues in Belgium, this is a nice one: http://www.beaufortblankenberge.be/index.htm (hotel you can rent for the weekend)
Definitely that part of Up!
Also when Gandalf is left behind in the mines of Moria.
Also very difficult when the characters themselves cry in movies...
