Yes it’s safe when spending overnights in tented camps. Note while on safari with Amazing Tours and Travel Co. Ltd you will be accompanied by licensed guides who are well trained and armed. On daily basis these guides share their lives with these wildlife hence have enough understanding of their behavior.
At your tented camp or lodge it is not uncommon for wildlife to wander through as camps and lodges are typically not fenced. An attack on a sleeping traveler would be highly unusual, occurring rarely when an animal has been frightened or provoked. Never venture outside your accommodations at night without your guide. Always consult with your guide/s when in doubt. While viewing wildlife there is a degree of danger as the behavior of wild animals cannot be guaranteed. However most animals are frightened by the sight / smell of humans and rather than attack, will flee (unless cornered or provoked). Attacks on humans are rare.
