We don't have a wedding block of hotel rooms, but recommend staying at this Hampton Inn or at Courtyard by Marriott San Luis Obispo

(1605 Calle Joaquin, San Luis Obispo, CA 93405) since they are within walking distance to the wedding (approx 0.9 miles to Filipponi Ranch venue).

Quality Suites Downtown San Luis Obispo

(1631 Monterey St, San Luis Obispo, CA 93401) is also a nice option if you want to stay downtown SLO. We also don't have a wedding block here, but wanted to provide this as a downtown SLO recommendation.
