I am not sure it was in the rulebook, but Mike and Vic have both said a hero may only receive the reward for completing a scenario/adventure/adventure path.
I would expect this is to stay in balance for the duration of the adventure path RotRL but since it is a co-op game you could also play with whatever house rules concerning rewards you want. :)

Can I keep replaying scenarios to get lots and lots of rewards?
You can replay scenarios in the hopes of acquiring better boons through exploration, but a character can't gain the reward for a given scenario more than once.
Resolution: On page 19 of the rulebook, at the end of the first paragraph, add the following:
"No character may gain a reward from a given scenario, adventure, or Adventure Path more than once."
