I think these are real vets sharing their R&R experiences.
Otherwise there's the infamous Times magazine article that featured this photo
I remember reading that Chiang baldie went bonkers when he saw that photo. Not because he was angry about such trades tailored made for US soldiers taking R&R existed, Chiang baldie himself got herpes from engaging sex traders in Hong Kong, so he isn't one to talk about anti-sex trade, but because he thought such things shouldn't be brought to the public. In fact, it was Chiang himself who ordered to make US R&R soldiers stay as enjoyable as possible.
The sad thing about that photo is that, Corporal Allen Bailey, Marine MP in the photo, was KIA in Vietnam before the article was published.
