If you have more time, consider adding a visit to the island of Corfu or exploring the Peloponnese peninsula. If you have less time, skip Nafplio and go directly from Santorini to Athens. Also, be aware that the ferry schedules and museum opening hours may vary during peak season, so plan accordingly.
