xenodochiophobia
n. fear of (or worry about) hotels

Art historian Bernard Berenson offered this word in his 1952 memoir Rumour and Reflection:

I invented it long ago to designate the sinking feeling that in my travels often overcame me: of fear lest the inn or hotel at which we were to lodge would be sordid, would not let me have the promised apartment; that my bedroom would have the wrong proportions, mulling or flattening me out of my normal shape and squeezing me out of my own way of breathing; that the lights would be glaring and no reading lamp by my bed; that there would be sharp or clattering sounds outside, or bad smells without or within. Motoring in the Vendee or Poitou, in Spain or Greece as evening darkened, tired or even exhausted, I would wish the destination farther and farther away, for fear of what I should find when I reached it.

When William Tazewell mentioned the word in a 1989 travel article in the New York Times, reader Louis Jay Herman wrote to add “a few more suggested contributions to the Hellenizing of the travel language”:

xenoiatrophobia
n. fear of having to cope with a foreign doctor

xenonosocomiophobia
n. fear of finding yourself in a foreign hospital

xenokleptophobia
n. fear of foreign pickpockets

hypselotimophobia
n. fear of high prices

And cacohydrophobia, loosely translatable as Can I drink what comes out of the tap in this joint?
