Less is more. Perhaps I'm less AR, but vacation is time for relaxing. I bring a detail spray and a couple of plush MFs, APC and a couple of utility MFs, a spray bottle of D120. No special glass MFs. I know I'll be doing a real cleaning and possibly a correction after the trip, so bug sponge can come in handy to get rid of the worst messes and I don't worry about marring -- which a detail spray will hide for the most part.
