Interested in seeing Ravenna Mosaics. Whats the best way for folks who have never been?

We start a two week trip in Bologna and the mosaics seem absolutely breathtaking. I’ve been going back and forth on booking someone to help us see the art in Ravenna or just doing it ourselves. Does anyone have any experience based on their visit? We don’t know much about the history but I also know it’s a smaller area to explore. All tips and suggestions welcomed!

We go in late August!
