Plan to spend the day in your swimsuit and cover up. In the night I wear summer dresses and hubby wears nice slacks with an island themed shirt. (Think Hawaiian shirt). You are not in your night clothes for very long and we go for 2 weeks, so we just wear the evening clothes more than one time and it works out fine.
I suggest 1 swimsuit for every 3 days you are there. Also bring some Woolite or something to rinse the suits out in and then you can hang them to dry. I also bring several cover ups.
Remember to bring a beach bag to put your beach 'stuff' in such as suntan lotion, book, beach towel, camara, etc.
Remember to bring lip protection as they too can get burned. A hat is also nice to have as my head always gets sunburned in my part and hubbies hair is thin so he also gets burned.
To save room, don't pack too many pairs of shoes. I pack one pair to wear at night, a pair of flip flops and my tennis shoes. It saves room and you really don't need to run a fashion show while you are there.
Prepare for beach gravity to set in and be relaxed. CSS is very romantic with lots of nooks and crannies to explore. We spent one afternoon making sure we swam and soaked in all the pools and hot tubs. You will have a wonderful time.
