Wet wipes or baby wipes are a life saver for me. I tend not to flush them though if a trash can is available - the bathroom smell is horrible enough, let alone having to drag some poor SOB in to unclog the toilet.
I'll also load up on Benadryl (to calm my nerves) and immodium to try to stave off the ass flood..
These things are freaking awesome for travel. (Not associated with the company in any way, just have a dozen or so boxes here 'coz I love them.)
Or individually packaged wipes. I always carry two in my pocket and keep a few in my car. It's a little more discreet.
Check the temps before hand. This time of year is usually pretty chilly at night so bring hats maybe a scarf and extra layers. Also headlamps. And these things: https://www.amazon.com/Stall-Mates-individually-Vitamin-Biodegradable/dp/B00PRJT9RY/
There are flushable wipes. Here are some in travel packs:
@OP: lota or wipes seem equally hygienic for your bum. Comes down to preference.
These are way better than TP for the random, "oh fuck I've gotta shit right fucking now" moments.
Yes!! WTF?! So far I've been getting by with pantyliners and these
Regular pemmican or the honey/cherry free variant are great. Officially they need to be kept refrigerated (because this company does not use any preservatives). Unofficially, the whole point of pemmican is not needing any special preservation or refrigeration. I do store them in the freezer at home, but take a bundle on trips with me - I've eaten them after being in my back pack for about two weeks with no problems. (This of course might have import problems...)
Depending on import rules you might be forced to buy locally. :(
Wet wipes are a travel life saver.
My suggestion does not involve a dry tampon- ouch! But I have camped a lot needing to use the suppositories (not to mention SMEP) and wear a suit all day. Put it in early in the am, and use a pantiliner like you would with underwear with your suit. (This is my favorite trick in general, midday I swap it and still have clean-feeling undies). Ideally give yourself 3 hours or so before getting in the pool, and take the pantiliner off before you do, of course! But that's easy to do even in a waterpark bathroom, where a full change is not. Also, Cottonelle makes those flushable wipes in individual packets. That can be a very nice thing to have on the go. I was looking on Amazon, and I found these too and think they are less expensive and appear to have less unnecessary wrapping for travel packs/purse backup plans: http://www.amazon.com/dp/B00PRJT9RY?psc=1 When I camp, I am for less waste, so we bring the Scott wipes (http://www.amazon.com/Scott-Naturals-Flushable-Cleansing-Cloths/dp/B00J51O4FC/ref=sr_1_2?srs=7301146011&ie=UTF8&qid=1425837286&sr=8-2&keywords=Scott+Naturals+Flushable+Cleansing+Cloths) refill ziplock (note, despite what everyone says, they are not all that flushable but they do biodegrade when baby wipes do not... and Consumer Reports found Scott tested to break up the most/quickest.) We do not ruin national forest plumbing, we pack out and throw away what we use in the trash but these wipes can do something nothing else can-- get sap off the tent and mostly off cotton clothing. But it helps with feeling cleaner when away from showers for days.
For me, wipes make public toilets less frightening.
