Gilligan Fonts

If I was stranded on a island and could only bring 5 fonts with me, I would choose Didot, Century Gothic, Helvetica, Cochin, and Avant Garde. I'm not really sure why I like these fonts besides the fact that they are the most aesthetically pleasing to me out of all the other "regular" fonts. I feel like any of these fonts could make a design a lot stronger because of the class they add, whether they're serif or sans.
