We're going to South Africa for the month of February and would love to finish off with a short visit to Madagascar. We may not end up in that part of the world again for many years. I've looked through the forums and see lots of recommendations for tour companies but not much actual information. We'd be flying from Johannesburg and will ideally want a five day trip that would include lemur watching, opportunities to see other fauna and flora, and perhaps a final day at the beach. Any recommendations for a tour company? Is early March worth considering?
