I'm not a guy but............
You will have a great time. There is plenty of shade, bring a good book and relax. There is always something to eat and then you could drink
Seriously there are lots of activities on board. I'm sure you will have a wonderful time. If you are at a beach they have umbrellas and shade huts, etc. Most places offer water sports. You will most likely hook up with friends on board and maybe you'll find someone in the same situation. Don't be afraid to introduce yourself and meet new people. (Does anyone remember the Mad About You episode where Paul and Jamie went to a resort and kept changing their identities? One of my favorites!)People watching is excellent. Don't sweat it you'll have a blast. Have an awesome time!
