I don't know of any lodge accessible with a G5.. even if the runway is adequate, safe parking is not available anywhere..
Best option is Masai Mara park in Kenya. Fly the 5 to Nairobi, transfer the pax to Wilson Field (30 min drive from Jomo Kenyatta intl.), from where they fly a Twotter or some such to a lodge in the park (30 to 50 min flight).
Masai Mara has several upscale lodges, and the Wildlife is fantastic. A quick google should give you several names for lodges... I like Kitchwa Tembo myself.
For the crew, the Safari Park hotel in Nairobi is very nice..
