here is a small piece of information i can give you . Le morne peninsula is interesting and dinarobin is a good hotel nothing to say about this.
Yet one thing , it is far from shopping centres , places where you can roam , places where there is sight seeing and taxi will charge you high.
Reunion is excellent i've been there twice and its wonderful , trying booking good excursions.
Dont forget ask for honeymoon deals , you will get lot of goodies.
THe month of june also is good for honey as it is mild.
Bon voyage,
