I just called Citi to make a 5-night stay next week for Christmas, with Best Western. Since the stay was so soon, they transferred me to a CWT rep right away. She got my info and requested hotel, then quoted me the same "nominal" price as on the website. I mentioned that there was a web promotion that actually made it cheaper than using the 4th night free rate. She asked me how to pull that up on BestWestern.com, and after verifying the promotional rate, confirmed that she could book that for me and told me the 4th night bonus would apply.
So, like others, I'll have to wait for a while to get the refund, but I was happy that they said they would match the web promotional rate. Between the $90 I should save here and the rest of the card value, I've almost completely covered the annual fee already.
