Bah - cotton takes too long to dry! Go for that nylon/lycra stuff. I bought a pair of seamless undies that I swear by. They dry in no time at all and fit like a glove. And no, I look nothing like that girl in the photo. Gimme padding!
In a too warm climate or if you are going to do trekking, I would'ny recommend lycra, unless you want to end needing baby cream in uncomfortable sites. Pantliners are not going to keep you cleaner, but is definitively easier to wash the unders when you have to do it on the sink

Personally, I like a clean pair everyday and sometimes twice a day. Whenever I travel, even for overnights or weekend jaunts, I always pack more than I need. I'm going to Northern Europe in March for 12 days and I'm probably going to end up bringing 15 to 20 pairs. I also wear mostly thongs, so there is actually less material, but I do occasionally like a boy cut or full back to give myself a break. Also, I bring another ziplock bag to keep my dirties so they don't mix with the clean ones. (same for socks).
As far as the type of material, for health reasons, lean toward cotton. It may take longer to dry, but I'd rather have to buy an extra pair while waiting for the others to dry then have to deal with infections or irritation.
I look at our panties the same way the military looks at socks... change them often and keep them dry. It's also too sensitive of an area to overlook cleanliness, so I'd say don't turn them inside out to get twice the wear, and don't think a pantyliner (or 2 or 3) can substitute for clean panties.
Hope my insight can help you. Have a good trip!
PS - Love the term "under crackers"
i think black and tan would be more sensible colours
