Hello FT'ers

I am thinking of planning a trip to Namibia and Botswana in Late Dec/Early Jan for two weeks. I have spend a fair amount of time traveling East/Central and South Africa and am looking for some advice about a trip. I will be taking my 66 year old mother on the trip and looking for something low key (Read no car camping) and priced in the mid/high range.
My experience with East Africa was hiring a guide and we self drove SA. We would like to have a safari and hit the major parks. Etosha, Chobe and the Delta.
Can this be done in two weeks? Anyone know a good outfitter? Any other things not to miss in these areas. I know that two weeks is short, but the key here is to see animals and give my mom a trip of a lifetime.
Thank you!

Any advice or tips would be greatly appreciated!
