the general rule for crusing seems to be lay-out what you think you will need and then take half of that. You will spend most of the day on board in your swimsuit and cover-up. Bring a couple of pairs of shorts, tanks and or t-shirts for each day. Sneakers and water shoes/sandals as the beach sand and ships decks can get very hot. Some type of hat (baseball caps are most popular) sunglasses and SUNSCREEN. I aways carry a fanny pack (leave your purse at home) for my daily stuff(stateroom key card, a couple of bucks, credit card, lip sunscreen, comb etc) a small back pack is also a great idea for your shore trips you can throw your beach towel and snacks in there, leave room for your purchases!!
