I got one. When I tried to validate online it kept giving me an error message. I called, only waited on hold for about 7 minutes, and was able to book for next June. For our family of 5 (4 adults, 1 kid) it saved over $1k on 4 nights at YC. Right at 35% off the rate I can see online right now for the same dates. I was also able to book 2 additional rooms with the discount for family who are traveling with us. This is the second code I have received in about a 3-year span.
