Found out after speaking with a Diamond Honors rep that when you get upgraded to a suite, that has adjoining rooms, and seperate room numbers, that when the property reports your stay to Honors their computer cannot give credit for two rooms on the same night and kicks everything out. The same thing happens when you reserve and pay for two seperate rooms on the same night. They said you have to wait till you see that stay on your "hotel Summarys" page on Hilton.com and then call in and they will manually fix it
