One good tip is to make copies of them, so that when/if the front desk "misplaces" them, you have a backup. After all, they are equivalent to a hundred-dollar bill. Protect them accordingly.
I go down the before checking out and give the front desk the bonus bucks and state I will return for the updated bill when I check out. This seems to work for me. Never have I been told you need to hand them in when you check-in.
