I just played the fan scenario, False Pretenses, with the kids (8, 5) with the following modifications:
* Had them hired in the beginning rather than extorted into service
* Instead of having the boatmen burnt at the stake, I had them tarred and feathered (and the wood elves threaten to tak eall your stuff, put you in funny clothes and send you donw the river in a canoe so people laugh at you)
* Other typical theme softenings for kids
I encouraged them to watch for the Druchii as he dug his way into the mound. They tracked him into the lands of Naggaroth, but I had them "get him" before he could get his friends to come back. They hired the blacksmith to put steel over the gate and I had them find the priestess to make "magical glue" to hold it there.
Twas fun.
