Thanks again, everyone. Luckily, I got a great deal on the Neutrogena website and got 4 cans of 70 SPF and 2 sticks of the solid (good for the faces of squirmy boys, I hope!) for $20. I had coupons and free shipping, so it worked out great! I will likely hit Target in Mt. Pleasant before boarding the ship. We are going out of Charleston and luckily, we know the downtown area pretty well.
I will let you all know if we come back tanless.
