any
other suggestions?

Ear plugs again.

Maybe listen to music on headphones to lull you to sleep (never works for
me, just end up awake for hours listening to the music).

A pillow. Place over their head. Wait for snoring to stop. Leave really
early in the morning before anyone else wakes up. Best to sign in under a
fake name with that one.

Hit them until they wake up. Hope you get to sleep before them.

Lace their coffee with a bit of extra caffeine. If they can't sleep they
can't snore.

Grow your hair. Shave before you go to the hostel. Try to get a bunk in
the girls dorm.

Comb your hair, shave and wash. Try to get invited to a bunk in the girls
dorm.

Carry the snorer's bed into the corridoor/street/rooftop/nearby canal.
You'll need help with this (shouldn't be a problem tho - even his mates'll
help you get the bugger out).
