If someone asked me to carry something for them, I would refuse and feel obligated to report that person to the authorities. Sorry. Use solid sunscreen. I spent a month in South Africa in January and I survived and you can't possibly be any paler than I unless you are Casper the Ghost himself. For some people, checking a bag costs money and time, so I understand the reluctance to do so. But check out the solid sunscreens, they do work, if you use them under make-up. (Sorry, male readers, I do not know if they work alone.)
