Yeah, stuff. Stuff is good.
How about pick a letter of the alphabet, say "j", and try to get 10 photos of things beginning with that letter.
Or work with a colour theme - every photo must contain at least one object in the chosen colour.
As it's likely to be sunny, play with shadows.
I have to admit these days, when planning a photo safari, I tend to want to do it as early as I can to get morning light before it gets too bright or warm. I should also consider doing it later in the evenings, too.
Whatever, have fun.
