Rodrigues is a small and fairly primitive island. The appeal, in my opinion, is more for backpackers and for those who really want to get away from the crowd. If you want to be pampered, by all means extend your stay on Mauritius. (This is more from information we got on Mauritius, rather than from personal experience since I haven't been there.)
