For our anniversary this year we spent the day down at the Hotel Del Coronado. If you have never been there I highly recommend it. We have never stayed there but we have visited many times. The restaurants are incredible and the beach is amazing.
This time we had my daughter and mother with us, so it was not exactly romantic lol, but we had a wonderful time. We tried something new for both of us and at the spur of the moment took a painting class on the beach.
