San Diego is gorgeous. We both fell in love with SD. We stayed in La Jolla in an Airbnb right near the beach. We spent our one month anniversary on the beach and ate amazing mexican food. We also did one of the coolest things we have both ever done..
We took a sand castle building class! It was awesome and I HIGHLY recommend doing it if you ever get the chance. We had a private lesson with Kristine at San Diego Sandcastles in Del Mar. It took 3.5 hours and Kristine was a true artist. Our castle was Hogwarts/Harry Potter inspired. They are pretty simple to make..just A LOT of sand & water. The tools are simple too!
