Decisions, Decisions

So I am in Palm Springs and we swim ALL DAY! Awesome right? except my hair dries out at a tiny bit of chlorine. So the decision I have to make is swim and dry hair or no swim and healthy hair. Seems like an easy decision, right? Well we usually go out to dinner and I absolutely refuse to shower before dinner and not after dinner. Don't ask why but I have to shower right before bed. Chalk up another to weird things about me. And I will not absolutely not wear a swim cap. That would be giving in. Plus they're ugly. So, any ideas?
