After noticing that an existing 4-night Hhonors award reservation for Trafalgar Hilton stated 1 adult, rather than 2, I called HHonors so they could correctly note 2 adults, which I felt might give us a better shot at an upgrade. Though I was reassured that nothing else was changed on the reservation, imagine my shock when, a few minutes later, I checked my account and discovered that 170,000 points had just been deducted! It took two more phone calls over a one hour period - the first to a particularly confused and unhelpful Customer Service Rep and the second to a more competent rep who actually understood the situation- before this was finally straightened out. Moral of the story: always check your account and never assume a Customer Service Rep knows what he/she is doing.
