We booked a six day trip through DumelaBotswana and it all worked fine. The first 3 days were at OddballsCamp in the Okavango Delta, and the last 3 in Kubu Lodge on the Chobe River.

It cost us $3,000 all up for the 2 of us, from including flights Maun -> Delta and Delta -> Kasane and road travel Kasane -> Living stone.

We went to Kubu Lodge because Chobe Safari Lodge was full. We went out on early morning trips and say elephants, lions, giraffes and lots of antelopes. Then we went by boat and saw loads and elephants again, as well as hippos and crocs.

Note that this is close eough that you simply have to visit Vic Falls -- either as a day trip, or on the way to the airport if you're flying out from Livingstone.

We loved it -- nice people, everything you need, quiet, clean, and not pretentious (if you don't know what I mean, have a look at the terrible, kitchy Vic Falls Sun)
