Well, I have only done the sunrise safari and I loved it! I am thinking about doing the sunset safari during my December trip. So I guess that I can't really give an answer, but I will post the differences between them:
Sunrise safari:
- Occurs at AK very early in the morning
- Only costs about $50 or $60 per person
- Requires admission to AK
- includes a buffet breakfast at Pizzafari after the safari
- you are out on the savanna for about an hour
Sunset safari
- Occurs on the savannas at AKL/V
- Costs much more : $150 to $200 per person
- Is much smaller group than the sunrise safari
- Includes a family style meal at Jiko
