Planning help

Hi there, We are two people looking to do a great migration safari in first week of September next year. I’m thinking around a week and including Masai Mara, Nakuru, Naivasha & Amboselli. I would prefer an open vehicle and to stay at some unique lodges where you can also see animals whilst there. What is the best way to get best price for a safari package and nice accomodation, is it to book separately or is it too tricky? I’m not sure how to go about it if separate as a lot of packages include accommodation? I would like to go with a local, knowledgable co if possible as I find it’s cheaper and they are the experts at what they do, more so than the bigger international operators. Any tips, recommendations are all welcome! Thanks
