Old Man Dies and Kids Give Him a "Viking" Funeral.
 

The movie I am trying to find is set in Britain, in color, probably from the early 2000 and a British production, the action takes place at the seaside, there is a funeral or something related to a funeral, it happens in a hotel o resort where people (family members?) gather, there is an old guy who eventually dies and kids who help him... but the most relevant thing is that they often talk of a "viking" funeral and when the old guy dies, the kids (young persons?) give him a "viking" funeral, putting him on a kind of raft, setting it on fire and leaving it to the waves of the sea...

Thanks!

A bit later than your stated timeframe but .... What We Did On Our Holiday?
