I believe I will be spending maybe a week in Kythira over the summer, but I will have a few weeks left in Greece. What are some places that make sense to visit in addition? It can happen either before or after Kythira, doesn't matter. I do plan to spend at least a few days in Athens before heading to Kythira. Are there some islands that are easily accessed from Kythira by ferry that are worth visiting? Maybe somewhere in the Peleponnese? I am open to suggestions.
