For Africa: Egypt and Jordan to see the pyramids and Petra. These 2 countries are good to visit on the same trip.
South Africa should be high on the list to visit Cape Town. Truly a great city to visit
Victoria Falls for Zambia and Zimbabwe. 2nd best waterfall in the world. There is a nice safari park in Botswana across the border there too
Rwanda for a gorilla trek. It’s one of the best things to do in Africa
Madagascar has the Avenue of the Baobabs, which is truly amazing.
