These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
The River Rock Inn was pretty much Squick incarnate. From dead bugs littering the rooms, to dust and dirt accumulating everywhere, to sheets stained with semen.
The stained bed in the Monticello Hotel episode is even worse. This time, the mattress and sheets in question used to be in the owner's house, so everyone immediately knows whose semen is staining the sheets.
After first seeing the pool at the Meson de Mesilla from a distance, Gordon commented on how it was "full of crap." When he tried to take a swim the following morning however, he found out that his throwaway remark was literally right.
Ugly Cute: Gordon's dog Rumpole, that we meet in the Four Seasons Inn episode.
