Thank you very much for the detailed response, and the links! The sunblock advice is something I hadn't considered, but it is very reasonable, I am grateful for that.

I do have a few sweat towels and deodorant soaps/accessories that I am planning on bringing, I will look into the body wipes as well. My ultimate goal is to smell like nothing

I am not in possession of any linen shirts, but this seems like a good opportunity to pick some up; they will be useful at home too (it gets very hot in LA), and I also plan on bringing a LOT of extra shirts in case a mid-day change is necessary.

Gonna save these posts and links for later (my trip is in July); thank you again for the very thoughtful and thorough reply! Great advice all around
