Best camera for an African Safari

I am an intermediate/beginner, I'd say.  I am going on an African Safari in Nov. and do not want to lug around a big, bulky camera but would be crushed if I didn't get great photos and videos!!!  Zoom is important as well as stabilization since I will be in jeeps, etc. bouncing arounds hopefully getting shots of animals along the way.  I do not plan to blow pix up beyond 8x10 or 8x14?   Which camera would be best for this type of trip/experience?
