No summary of stays/nights shown with account
If this has been reported, I apologize.
Until recently, whenever I brought up my account on the Hilton website, it showed the number of stays and nights I have in the current year. Thus, you could easily calculate how many stays/nights you need to retain Gold or Diamond status. This info is no longer available. I emailed HHonors and asked where I could find this info, and they replied it is no longer provided. So you have keep your own running total. This is very user unfriendly!
