A good reminder for folks: Whenever you are at a hotel, charge back whatever you can to the room. Most likely that final room charge will count towards travel. I just noticed that a bunch of ski tickets I purchased at the resort desk instead of at mountain got 3x.
On the flip side....a bunch of gift cards for restaurants I purchased through Open Table for the holidays showed up at 1x. Lessoned learned, buy restaurant gift cards directly from restaurant!
