Planning a safari trip to South Africa (near JNB) next May and will likely be adding a side trip to Victoria Falls. I have a few questions:

1) Only one airport serving that area?
2) Zambia side or Zimbabwe side?
3) Is it easy to go from one side to the other?
4) Hotel Recommendations.
5) How long shall we plan to stay? 2 nights enough?
6) I understand Devil's pool will not be accessible in May. Is that the same for Angel's pool?

Thanks in advance for any help.
