I was wondering what the best way to send a letter is? We just got back from SSR, our first time there. It was a lovely resort but we had a few too many issues there with the room (dirty bathtub, leaking washing machine that never got fixed despite 2 days of phone calls, etc). Concierge told me to send a letter...but do we do it to DVC or Saratoga Springs or what? Any suggestions are appreciated!
