Does anyone have a coupon for Expedia to book online?

My husband and I will be having our 9 years anniversary, unfortunately we have to bring our 3 children. One 5 month old, 3 year old and 8 year old and nobody is willing to take them all ( and I don’t blame them). We were wondering to just stay in a hotel in San Francisco just to get away from our daily routine. But we are on a budget and hoping to book soon. If anyone have a spare coupon code from Expedia and willing to share, would really appreciate it. Thank you!
