I'm not sure what kind of renewal of vows that I want to have for our 10th wedding anniversary?

Me and my husband live near the beach, but he won't have it there. I wanted to have a formal dress he wants casual ie: Jean, on down shirts etc. He wants the mountains, and I want romance, elegance, and private. We both know that we want something unique,special, and low key to celebrate our 10th wedding anniversary, but we can't come up with anything that we really like. Part of the planning depends on when he's deployed, and when he comes back. No guests or family will be invited. This is strictly just for me, my husband and our children. Anyone have any ideas? I'm open to helpful suggestions.
