I’ve been to a variety of hotels in my 31 years and they all seem to share the same upside-down plugs…meaning the hole for the third prong is above the two parallel plug holes rather than below.
Now, I only notice this in the bathroom because that’s where I’m always plugging in a hair-dryer, so I’m not sure if it goes for the rest on the outlets in the room. However, it seems to be a very consistant feature in bathrooms from Holiday Inn to The Four Seasons.
What gives?
