Is there a place in the universe where everything is so far apart that it would seem like complete darkness if you were floating around?

Most of space is like that.

If you look at the sky, the majority of the lights you see are from stars within our own galaxy, and most of these are nearby stars less than a few thousand light-years away. Beyond that, you can't see individual stars - you can only see the general wash of faint light that makes up all the numerous stars of the Milky Way, our own galaxy. You can also see three other nearby galaxies - Andromeda, and the two Magellanic Clouds - but these are pretty faint and you need fairly dim lighting conditions to see them. They are also quite close as far as galaxies go - Andromeda is millions of light years away, and the Magellanic Clouds are hundreds of thousands of light years away. These are all galaxies within our "Local Group" of galaxies.

So if you left the Milky Way but stayed within the Local Group, you would lose most of the light (because it comes from nearby stars), but keep a few dim galaxies visible as faint splotches on the sky.

But of course we can do better than that. Groups and clusters of galaxies are small blobs where all the galaxies are concentrated. These blobs are arranged in "filaments", and there are huge voids between these filaments. The universe is mostly empty space, with clusters and groups of galaxies taking up only a small fraction of it.

So from one of these voids, you would not really see anything. You wouldn't even need to go very far away from a galaxy cluster for the sky to be almost completely dark. If the only galaxies that appear big enough to be visible with the naked eye are millions of light years away, then moving tens of light years away would cause most of those to disappear. We can't even see the Virgo Cluster with the naked eye, and that's only 65 million light years away.
