I was also looking at Mapito; we have just shy of 400k BonBlah points, but I don't think there's any way that we can get another 400k in the next few months. Maybe a good transfer offer from AmEx or Chase will roll around, then I'd consider moving points to make the trip happen.
@calypso726 I understand your fear -- those night walks back to your cabin are no joke. Biggest scare we had was in Zambia, leaving our cabin in the morning for the walk to breakfast; the cabins were round-ish, as I was coming around the side of our cabin, about 4' from me was a hippo munching the grass. I grabbed my dd (who was on her phone just behind me) and we ran for our lives back to our cabin. I called for an escort to breakfast once inside. It was broad daylight -- for a hippo to be out of the water was unusual, so it was very unexpected. People asked if I got a picture -- duh, no I didn't stop to take a pic, that split second could be the difference between life and death. Hippos are one of the most dangerous animals in Africa to people.
