Good morning, I have writen an answer before but it got lost it seems, so lets try again :-)
Ok Kruger National Park is big and offers a big variety of accommodation throughout the park as well as outside the gates. What accommodation you pick will depend on what you intend spending. Your time in the park should be at least 4 days not meaning the day of arrival and departure to be counted. You have a huge net of roads you can travel and plenty of game to be seen so please take it slow and enjoy your stay. You can include Kruger Park into an itinerary you need not do it seperately
