In that case it may be worthwhile considering the Le Victoria. We have been there three times now and really like it.
There is a high percentage of couples coming there almost every year, which always is a good sign.
The place is perfectly managed, food is good, you will find a lot of choises looking at watersports, but also volleyball, Tennis and the like.
The hotel is a good basis for sightseeing, too.
You should always use a taxi for daytrips. They will charge you about 30-40 Pounds a day.
If you want to participate in organized tours, you should go to Grand Baie. There is an agency called Ebrahim tours, which we found both absolutely reliable and reasonably priced. Don't book any tours in the hotel or via your travel agent, the local choise will be much more attractive.
Immer wieder gerne auf Mauritius und im Meer darunter ;-))
