I especially like the last one, so I'm not the only one who has cursed at the morons who design them seemingly so that the spray of the shower will go right where they put the place to put your clothes. I have sometimes imagined some frustrated designer who is secretly thinking, "that'll teach em for not getting a hotel!", well, not really, but it does make you wonder sometimes what they were thinking when they made the design (probably simply its an oversight, and these places are built to be the least expensive so done quickly).

When we go car camping and take bikes, I always have panniers with me for day rides and such, so a ride to the showers using a pannier has been handy many a time for what you describe.
