When the first person used "hotel" in an English sentence, they were struggling to find a suitable word and failed, and fell back to another language for it. Or possibly they thought it was a better word than the English equivalent for some reason. They thought of it as a French word, with all the implications of it in French, rather than English.
When I use "hotel" in a sentence, it's just part of the language I grew up with. To me, it's an English word, not something I fell back on in another language.
That said, the "Spanglish" referenced here is being learned from birth by people, so they aren't context switching either. They're just speaking how they learned to speak. Older people are probably still context switching, but younger people likely aren't.
