Although I agree with others that this happens often (and is easily fixable) my last 5 stays have not posted correctly - WAY off...as the OP says.

Odd that is happening so much more frequently, and in such a huge point differential. Really odd in that Diamond points etc are posting....but not the base points. ($700 bill, got 900 base points)

Also found an instance where the stay points posted (albeit incorrectly) - but with no night or stay credit. Since it was booked directly with Hyatt, do not see how I could have been on an ineligible rate.

In total, I am missing over 10K in points and 3 nights credit for only (3) different hotels.

For those who do not regularly check their account - this might be the time to do so..........
