I would also be in for this! I am soooo tired of having to call..and sometimes MUCH more then once!
Why not do as a real hotel chain (Hyatt) does, and put the codes for the bonus ON the receipt? 500p or something like that under rate code? Then MR can nail them with PENALTY points!
Penalty points would be something like:
500 for posting properly...
3000 BONUS for NOT posting, plus the 500....
That will make the hotels ENSURE they post!
