30+ trips in the last 12 years, and I'm an avid sunscreen profit. I do the spray on 50+ proof (sometimes 70 or 80) first thing, then again before the pool mid day and then again before we go out in the "evening." I just carry one of those sun block sticks with me, a bit of cash, my id, my cc, iphone, a lip gloss/chapstick, and MAYBE a mascara if its evening and I'm feeling really froggy. All can easily be stored in a small wristlet, or pockets. I've sewed pockets into several cheap cotton dresses and it was a breeze.
BEST OF LUCK!
