Mine usually show up ~3 days after the stay, but I still have a stay from 4/15-4/17 that hasn't shown up yet. However, my 4/17-4/20 stay at another hotel is already on my account. So, I'm thinking that it depends upon the hotel, and perhaps the number of guests they're processing (the one that hasn't shown up for me yet was the Detroit Ren Cen, while the CYs I stay at always post quickly).

To the OP... do you get your bill receipt emailed to you after your stay? I've found that the points usually show up when that comes in to my email account. Looks like that's true in the recent stays as well - the email receipt for my 4/15-4/17 stay hasn't shown up yet, but I got the one for the more recent visit.

If it's been >10 business days, I'd go ahead and email or call MR.
