Many resorts offer excursions to sandbanks or small desert islands. A private trip will give you the whole island only for yourself. In some resorts they would drop you at the sandbank and boat goes back to resort, just tell them when you want to go back. As you as you reach the sandbank its time for you to enjoy your own world. You can enjoy a bottle of champagne, it goes well with a cheese platter. Take a lot of pictures with different poses.
If you want some fun, dig a whole in the beach and bury your partner, keep only the head above. Put some sand where the body is buried and make a mermaid. Take pictures. Get crazy. Have some sleep. Get relaxed and forget everything else. After the trip you will feel your biological clock got a reset.
