I need help from all the water and sun lovers. I am going to purchase more sunscreen for my trip but can't decide how much to buy and what SPF to get. I am guessing 5 bottles of the spray kind of sunscreen. I don't want to run out and can always take the left overs home. Maybe a SPF 15. Or should I go SPF 30? Hmmmm... so many decisions. Opinions please!
