For us, while it is not exactly business as usual, we are still operating and already assisting some clients with plans for 2021 (Australians do not expect that we will be permitted to travel to most destinations until next year).
Our expectations are that while many locations will start to open during late 2020, most will not be accessible until next year. We certainly don't see safaris really starting until the middle of the year, though we do expect demand to be very high as globally people start to catch up with their lost love of travel.
When you start planning your next safari start talking to us, and remember that through our sister agency "Journeys Unlimited" we can assist you to any destination.
