ATAB and Croooozin:
Although we are a little of track, I agree with the getting up early and just sitting quietly.
We have done that many many times. My husband's favorite story is the time we were cruising and I got up early and went to the Lido deck and had coffee. He got up and also went to the Lido deck with his coffee. We were sitting quietly enjoying the breeze and calm ,when we both looked over and saw each other. He came over to my table and we laughed for a long while. We never knew we were on the same deck just across from each other for almost a half hour.
That is how relaxing it can be
