Late night post, both Founders and Caesars are closed (departments I need) and Founders will be closed for MLK Day.

I got a free 6 month trial that includes the match. It says it takes up to 3x weeks and I am arriving on February 1st. I am curious to know if I can just match it in person at the caresars rewards desk. I'd like to take advantage of the waived resort fees as my stay is 4 nights.

Thanks!
