The Maldives is built for total seclusion: overwater villas, a single resort per island, and very little to do beyond the reef outside your door. It is the better choice for honeymooners who want the world to disappear for a week.
Mauritius, by contrast, is a full island with a mainland feel — botanical gardens, waterfalls, rum distilleries and markets alongside its beaches. That variety makes it a stronger fit for families or multi-generational groups who want more than one kind of day.
If you are torn, ask what your ideal afternoon looks like: a hammock over the lagoon points to the Maldives, while a day exploring Chamarel’s coloured earths points to Mauritius.
