I have lost most of my tan from our earlier summer beach trip. How many of you did the tanning beds before going to Mexico? I just don't have time to go lay in a tanning bed but I don't want to burn too much either. What Spf did you use in Mexico and still able to get a light tan? I'm not a big lay out in the sun freak anyway. I will either be in the pool or doing some type activity other than just laying on a chair all day but I don't want to be miserable from sunburn.
