If you're staying for a couple of days or a week, we suggest you stay by the beach and uber/drive to the wedding. The coast is the best place to be, and we will be having an afterparty at our hotel by the beach. The day after the wedding we'll be hosting a beach day/lunch for anyone who wants to come :)
Our favorite places by the beach are: Carlsbad, Encinitas, Solana Beach, Delmar, and Cardiff.
Our favorite places inland are: Rancho Santa Fe, Rancho Bernardo, 4S Ranch, or San Marcos.
