Happy to hear you are out there making fun! The one thing teardrops do is attract attention...A good thing because people will look out for you....not so good because you are noticeable! I am thinking I will get one of those small boat horns too..

You can use the panic button from your tow vehicle's key, if you have that feature. Something that startles people and makes them look, especially in a campground, is yelling FIRE! Also, some flashlights have built-in alarms. Probably the best thing to do, though, is to visit the restroom before you go to bed and plan ahead with ways to keep from leaving the safety of your cabin until daylight.
I've thought, for peeping Tom problems, to place a few set mouse traps under the windows, with some leaves over them. That might end up being fun!

Of course, that's provided the window isn't part of the door...wouldn't want to give
yourself a rude awakening.
(Oh, I'm in a rare mood tonight....TeeHee!) That method would probably work with four legged animals, too. (When a person wants to train a pet to stay off the couch, They sometimes set mouse traps on the cushions with newspaper over top keep the pet from being hurt but the 'snap' sound scares them away from the item.)
