The distance to Andromeda is about 20x times the diameter of Milky Way. But of course this is massively longer that hopping from a solar system to the next.

Point of interest, we'll meet Andromeda in about 3 billion years or so. Point of additional interest. Due to the expansion of the universe, it is impossible even in theory to travel to most of the galaxies that we can see. Point of amazement. Our telescopes can pick out more galaxies in the universe than individual stars!
