Beware of the cameras with lenses that fold out of the body when turned on and then pull back into the body when turned off. These suck a little air into the camera each time. Dust can come in with the air and then settle into the camera destroying the delicate mechanisms and dirtying the lenses. I would instead recommend a ruggedized sealed camera, ideally one that is at least wetproof if not waterproof to a meter or so. I learned this the hard way.
We have two Casio Exilim EX-V8 cameras in our family. They are inexpensive, take good pictures and have the sealed lenses. This camera offers fully automatic which my wife likes, shutter priority, aperture priority and fully manual which sometimes I like to have. It also has a 7x optical zoom which is wonderful. Do not be mislead by "digital zoom". Only consider the optical zoom when making a comparison of cameras.
I've also had Canon and Nikon high end cameras for decades. That's top quality but a higher price and you may not need that.
