I wanted to reach out and see if anyone has made the same mistake I have or any advice. About a month ago I booked the Park Hyatt Paris Vendome for 4 nights but on separate reservations using free night certificates. Today I find out instead of booking August 9th, I mistakenly booked June 9th, not sure how I managed to miss that one! Today the hotel reached out to me and asked if I had meant to book August 9th instead and has graciously moved the free night certificate to the correct night. At the end of the so far great email was the bad news… they had charged me for June 9th. I reached out to Hyatt, but the hotel refused to consider reversing the charge for the obviously wrong reservation because the French Open was that weekend... I have the worst luck! I spoke with 2 different Hyatt representatives and was told the decision was with the hotel management. Does anyone have any advice on how to get this charge reversed or been in a similar situation?
