The beach and resort side of Mauritius is definitely appealing, but I would also want to explore the island. I normally look for practical travel guides before visiting a new place because they give me ideas beyond the usual tourist spots. For European trips, something covering what to do in Copenhagen can be a handy starting point. Then I would use the same method for Mauritius and look into nature, food, beaches, and local culture. It is always better when a trip has a rough plan without making every hour feel scheduled. That way, there is still plenty of room to discover something unexpected.
