How to be a happy vampire in the sun

I have pale skin, and I enjoy having pale skin. I dislike the beach, tan lines, sun damage, and 100 degree heat. However, in mid-July, my husband and I will be staying for a week in a Galveston, Texas beach house. Do any of the Homies have advice for keeping the sun off while keeping cool? (Other than liberal application of sunscreen, of course.)
