people take things a little to serious. locking people out of a dungeon for dying is insane. if a group take 3 hrs to clear a dungeon and die 100 timeskittenright they deserve to finish it as far as im concerned. they have earned it maybe not by your standards but i have. now the part that i do agree with maybe extra tokens for for dying less, more gold, maybe make it timed. Ill tell you this if you have a gripe try to come up with a solution that makes everyone happy not just yourself . it isnt hard if you brainstorm.
