I posted this over on the Volcano Bay thread - adult rash guards are usually super expensive, but I burn easily and we are going to Universal in August. I noticed that Target has ones for kids at 50+ upf. I weigh 128 and am 5'5" - the large boys/girls both fit me tightly for swimming, and the xl fit great for a loose fit. They are $12.99 each, and are currently 20% off of that with the code "SWIM" - the men's gray "Goodfellow" rash guard is on sale for $12.59 I bought a bright green one in the boy's department, and a white one with "Swim Like a Mermaid" on it in the girl's department.
