I don't usually use a lot of sunscreen at home (I live in the frozen north, though I know that is no excuse). How much (how many ounces) of sunscreen will I need for my 7 night cruise? Also, has anyone used Blue Lizard sunscreen. I am considering getting that kind and I am trying to decide between regular and sensitive formulas. I am very fair, but not really allergic or sensitive to skin products. Sorry it's a little off topic, but if anyone can help, that would be fantastic!
