No homebase

So I'm running a session with a small group. The idea of the world is that it's being invaded by a "shady force ". I wanted my players to be always on the move as the invading force chases them across the continent. This means a homebase only lasts for a few irl hours. Is this a problem do you guys and gala thinks? Should I add one in or keep them as nomads?

This is my first time DMing so any advice is awesome to have!
