If you are struggling what cameras and lenses for this trip, here are some practicle suggestions. On Guilin photography tour, you will need a zoom lens to shoot highlight spots that you can't reach, a fixed lens for portraits, and a wide angle lens for landscapes. You gears will be heavy, but it is the photography.
If you are a tough guy, take two. Will save lots of time to change lenses, easy to capture some evanescent moments, like the golden light in river, ray of sunshine on rice paddies, and moving buffalos on the riverside.
Of course, one camera with one lens is fine. The lens is better be an all-cover, can shoot landscapes and portraits. 24-70mm f/2.8 or 18-108mm f/4.5-5.6 are good.
