That shouldn't be an issue, we'd recommend letting us know about this at the time of booking.
I would recommend July/August. In the later months the temperature increases, so generally its better to travel around July if your focus is wildlife viewing and comfortable exploration.
In the game reserves of Botswana, our campsites are exclusive to our groups and the exact location can change slightly as the campsites move short distances to allow the bush to regrow. Tents are canvas en-suite with open-sky bathrooms featuring a toilet and bucket shower. In Chobe National Park, we stay at a permanent campsite located at the point where Zambia, Namibia, Zimbabwe and Botswana meet. Situated near the water's edge, each tent is built on a fixed platform and has an en-suite bathroom with a sink and flushing WC.
Visas are not required by UK, Australian, New Zealand, US and Canadian citizens. All passports must have at least 6 months validity remaining from date of entry into Botswana. As for Zimbabwe: A double entry visa is required for UK, Australian, New Zealand, US and Canadian citizens. British citizens can obtain these on arrival (us$ 70), all other nationalities should consult their consulate. All passports must have at least 6 months validity remaining on entry and have two consecutive blank pages in their passports which lie side by side when the passport is open (i.e. a left and a right-hand page).
Hard to say as you cant define the travel time during safari as sometimes you have to travel further to find the animals. We cover approximately 1000miles of ground +/- 100miles by road.
Technically, Moremi is within the Delta, and there are several water reservoirs where activities such as mokoro canoeing are possible. However, if the main interest is to visit the Delta itself, our Botswana tour (trip code BW) travels to Shakawe, where we spend a number of nights on a simple houseboat, allowing for a more immersive Delta experience.
In the dry season (May-Oct) Mosquitoes are generally low, especially in classic safari areas like Chobe, Moremi and the central Okavango. Many people barely notice them. In the rainy season mosquitoes are more noticeable, especially around permanent water like the Okavango Delta, riverbanks and in the north. They are usually worst just after heavy rains and at dusk and dawn.
