First of all, I just wanted to thank everyone for all their helpful hints, suggestions and reviews. I relied heavily on all the advice on this forum when booking my trip and I definitely couldn't have done it without you!
I do have a question regarding my visits with the tribes. My tour operator has two visits scheduled during my safari: a half day visit with the Hadzabe Bushmen and two full days and nights with the Maasai Tribe. My TO promised that these weren't the typical tourist performances but rather authentic experiences (this remains to be seen) but, either way, I'm not sure what to expect and how to behave. I don't want to accidentally insult or offend anyone. I know it's rude to take photos without asking permission but that's about all I know. Are there any other "faux pas" I should be aware of? Is it customary to leave money or gifts? Is two full days and nights with them too much of an intrusion?
Thanks so much for all your help!
