We are traveling in Feb. 2014 and have settled on Buhoma area for gorilla trek. We have eliminated the H group because it appears they travel widely and could be the most difficult to track. That leaves Rushegura and Mubare. Is Mubare still only 6 members? Any advice on which to choose? We are 3 women in mid 50's and 60's. We will also being doing a 2nd trek in Rwanda. Thanks in advance!
