We are planning to travel to Ruhengeri this September after our time in Kenya however we are only able to secure a single day's permit. We had hoped to obtain two day permits but they are already sold out. Has anyone missed seeing the gorillas on a single day? I know the guides are excellent and have a very good idea about where the groups are but it would just "gut" me to miss them. Also, since a 2nd day isn't available, opinions about the golden monkey permits?
